Subject: EUVE NRA information
Attention,
The following is a message from the EUVE Guest Observer (GO) Center about
the EUVE NASA Research Announcement (NRA) for Cycle 3 of the GO Program. It
is intended for those of you interested in submitting GO proposals. Thanks ...
Brett Stroozas
EUVE Science Archive Manager
----- NRA Message from EUVE GO Center -----
The third EUVE NRA has been mailed out, and should have reached you by
now. This news bulletin contains information on getting the complete
appendices to the NRA, notes on some of the appendices, and on the pro-
cedures for submitting the electronic parts of your proposal.
We recommend you read this bulletin with a copy of the NRA and appendices
and forms, including a current copy of the EUVE Guest Observer Handbook, at
hand. If you have not yet obtained them, read on.
-------------------------------------------------------------------------------
I. GETTING THE COMPLETE APPENDICES TO THE NRA
-------------------------------------------------------------------------------
The NRA mailing includes the announcement and Appendix A, which outlines
the EUVE Guest Observer program. Appendices B-H can be obtained either:
1) electronically, using the WWW URL or ftp site given on the last page
of the Announcement,
or
2) in hardcopy by request to the Project Office at GSFC.
Although the email address for the GO Center is listed under
"E_MAIL REQUESTS FROM:" on page 2 of the Announcement, mail to this address
will generally be answered with information on using the electronic facilities
(also given below in this bulletin), or redirected as requests for paper
copies to the EUVE Project Office at GSFC.
1.A ELECTRONIC COPIES VIA WORLD WIDE WEB
-------------------------------------------------------------------------------
If a WWW browser such as Mosaic or Lynx is available to you, this is the easiest
way to obtain the NRA materials. Use your Web client program to open the URL for
the Center for EUV Astrophysics (CEA):
http://www.cea.berkeley.edu/HomePage.html
and select the icon for the EUVE Guest Observer (EGO) Center. Select the
link "NRA" to enter a "shopping page". Click on one of the underlined links
to order your file selection and a transfer will be initiated. A dialog box
will appear for you to enter the directory where you want the file. This
process can repeated for each file, or you can get the entire NRA in a single
compressed tarfile.
If you do not have access to a WWW client, you can get the NRA materials
from the WWW using telnet:
%telnet ftp.cea.berkeley.edu 200
A session in Lynx, the text-based Web browser, will be started automatically
at CEA. You must first specify your terminal type; enter the default, for a
VT100, by typing a return. This works pretty well for most terminals, including
xterms. You will be given a menu that represents the CEA HomePage. Select
"NASA Research Announcemnet for EUVE Guest Observer Program," by pressing the
down-arrow (2 on the keypad) until it is highlighted, and press return. This
will put you on the NRA "shopping page." You can open and read any ASCII file,
such as the electronic "proposal form" file, by selecting it with the down-
arrow, and typing a return. If you want a copy, select the filename and type
"p" for print. A page with printing options allows you to mail the selected
file to yourself. This method of receiving the NRA files is subject to limita-
tions on the size of email messages.
1.B ELECTRONIC COPIES VIA FTP
-------------------------------------------------------------------------------
The Appendices for NRA 94-OSS-13 may be obtained via anonymous ftp at the
CEA. The site addres is:
ftp.cea.berkeley.edu
OR
128.32.154.12
Use the following procedure to extract files containing the NRA materials
via ftp:
%ftp ftp.cea.berkeley.edu
Log on with username ANONYMOUS;
the password is your COMPLETE EMAIL ADDRESS.
Set the file transfer mode to binary:
%binary
Go to the nra directory:
%cd /pub/nra94
There is a README file with further instructions.
To get a copy, type:
%get README
To get a compressed tarfile with the complete NRA type:
%get NRA.tar.Z
Note: Your site may be set up to uncompress the file
"on the fly".
The appendices are also available in smaller separate files.
ASCII versions of most files are now available. Figures for Appendix G must
be requested. Send postal mail address to egoinfo@cea.berkeley.edu.
If you have difficulty with the ftp site or technical questions in
regard to instrument performance, please contact the EGO Center by
sending e-mail or calling:
egoinfo@cea.berkeley.edu
(510) 643-5056

II. PROCEDURES FOR ELECTRONIC SUBMISSION
Certain parts of the proposal must be submitted in both electronic and paper
versions. These include the Cover Page, General Form, and Target Summary Form,
with the addition, for spectroscopy proposals, of a sample signal-to-noise
calculation for one of the proposed targets. Copies of these forms which have
been obtained electronically are acceptable for both paper and electornic
submission. A copy of only the electronic forms may be obtained as the file
"Forms.txt" from the CEA anonymous ftp site.
NOTES TO PROSPECTIVE PROPOSERS
@ Item 3 does not mention the necessity of including a sample signal-to-noise
calculation with electronic submissions for spectrometer observations.
Notes on Appendix C:
@ Section I, page C-2: the electronic submission must include copies of
the Cover Page, General Form, Target Summary Form, and for spectrometer
proposals, a sample signal-to-noise calculation (worksheet in Appendix D).
The table on C-1 only mentions electronic submission for the Target Summary
Form. The signal-to-noise calculation need not be submitted electronically
for proposals that use only the Deep Survey and/or Scanner instruments
(including RAP). These proposals DO require a Technical Justification.
@ Section IV, "moving target": a moving target is one that is close enough
that the spacecraft cannot track it continuously, but must make frequent
(>= 1 per orbit) updates. These include the moon, planets, and comets.
The ephemeris provided in the Special Requirements section should give
the object's position at a resolution of 1 per day for comets and the moon,
and 1 per 3-5 days for planets. This ephemeris is used only for determining
whether EUVE can observe the target during the specified period.
@ Section V, TECHNICAL JUSTIFICATION, the sample calculation required for
electronic submission is a signal-to-noise calculation, as summaraized in
the worksheet at the end of Appendix D. The Technical Justification need
not be submitted electronically, although the worksheet appears on a page
labeled "TECHNICAL JUSTIFICATION FORM".
@ In section X, RIGHT ANGLE PROGRAM SUBMISSION, the phrase "no observing re-
quirements allowed" refers to special pointing requirements. Right Angle
Program proposers may not specify spacecraft roll angle, coordinated
observations, request phase coverage or contiguous observing time.
@ As stated, in section X, a RAP proposal may be submitted electronically,
in its entirety. Science Justifications should only be submitted elec-
tronically as part of a RAP proposal. RAP proposals DO NOT require a
Technical Justification.
Notes on Appendix D:
@ The form for electronic submissions is an electronic form, available as an
ASCII file via ftp or email as inticated on page D-1. The file also in-
cludes spaces for a Budget Summary and Institutional Endorsements, which
are not actually required for the electronic submission. These portions
of the file may be used to produce the corresponding parts of the hardcopy
forms.
SAMPLE S?N CALCULATION
Notes on the individual items in the "INSTRUCTIONS FOR SAMPLE CALCULATION"
The calculations in the sample S/N worksheet correspond to equations in
the EGO Program Guest Observer Handbook, although the nomenclature used
is somewhat different. To clarify the correspondences, the equation numbers
from the Handbook, and the labels from the Quick Reference section at the end
of Chapter 3, are given below each item where applicable, with any notes.
Underscores in Handbook references indicate subscripts. The word "script"
before a letter indicates the use of the script style typeface for variables
in the Handbook.
@ Units for Target_HI_Column and Target_HeI_column are cm^-2.
@ Effective_Area: Spectrometer channel effective area, in cm^2.
Handbook: A_eff(lambda)
@ Target_Flux: Model source flux at spectrometer aperture, after ISM
absorption.
Handbook: script F(lambda)
@ Target_Exposure: integration time. Note that required units for
the sample calculation are kiloseconds.
Handbook: script T. All times in in the Handbook are in seconds.
@ Target_Bin_Width: w, spectral bin width in Angstroms. The typical bin width
for emission lines is the spectrometer channel resolution element: .5 A for
SW, 1.0 A for MW, and 2.0 A for LW.
@ Background_Count_Rate: Background count rate in a spectral bin. Averaging
over the sample height of of the background area is implied. See the Guest Observer Handbook or the data files available via WWW or ftp for estimates
of instrument background count rates. The rates given are per Angstrom, and
must be multiplied by the bin width to obtain the count rate in a spectral
bin.
Handbook: B' = script B x w (eq. 3-4).
Note: paper copies of Appendix D acquired from the Project office may have
an overtyped line for this entry in the sample calculation instructions.
The explanation for this entry should read: "Expected background count rate
(photons/sec), integrated over the bin width."
@ Source/Bkgd_Height_Ratio: This is the ratio of the height (perpendicular
to the dispersion direction) of the projected spectrum aperture to the
height of the background region used for subtraction. This parameter may
not be applicable for diffuse or extended sources; see GO Handbook
sections 3.6.2 and 3.10.
Handbook: 1/n, using same definitions (section 3.6.2, eq. 3-3)
@ Total_Signal: S, total source counts in a spectral bin after integration
over time T.
Handbook: Equivalent to the Handbook's source count rate, S', multiplied
by exposre, script T. See equation 3-1 for line emission count rates,
equation 3-2 for continuum bin count rates.
@ Total_Noise: standard deviation of integrated source signal. Units are
counts.
Handbook: sigma_S. See Hanbook equation 3-6.
@ Achieved_Signal/Noise, also called signal-to-noise ratio, for line or
continuum bin.
Handbook: This quantity is equivalent to S/sigma_S in equation 3-9 for
emission lines, 3-10 for continuum bins. Definitions of S and B in Ap-
pendix D include multiplication by the bin width where necessary for
continuum sources, while these multiplications are explicit in the
Handbook S/N equations.
Notes on Appendix F:
A new version of the latest EUVE sky survey catalog is now available on the
CEA/EUVE ftp site.
