This page describes the output columns on the
FUSE Search Results page. For information about
FUSE and its data, see the FUSE homepage at
http://fuse.pha.jhu.edu/.
Use the FUSE Science Search form
to locate and retrieve observations from the FUSE data archive at STScI.
Both public and proprietary data may be retrieved through this interface.
The FUSE Science Search form offers a view of FUSE observations,
which comprise one or more exposures.
To locate individual exposures, use the
FUSE Exposures Search page.
More information about retrieving FUSE data may be found on
the FUSE retrieval help page.
General Results Options
Most mission search results pages have the following general
features/options. (Note that the sorting, paging and VOPlot
options all require JAVASCRIPT to be supported and turned on,
and the interactive plotting option uses HTML5 which is not
supported in Internet Explorer before version 9.)
Clicking on the column headings at the TOP of the
results table will sort the returned results based on the selected
field. Clicking the column heading a second time will sort the
results in descending order. As of August, 2014 sorting is now
possible with RA and Dec coordinates in sexigesimal notation,
and the previous bugs
whereby exponents are ignored in numbers using exponential notation
(e.g., 6.3E-3 is sorted as if it were 6.3), and signs were
ignored in floating point numbers have both been corrected.
Note however
that the sort functions (like many interactive features)
are written in javascript which is not always supported in older
browsers.
Alternatively, selecting the sort options in the initial query
does not depend on javascript,
and will sort the entire search result, not just the displayed
rows.
Clicking one of the column headings
at the END of the results table (or clicking the
"columns help" link at the top of the page) will display
help information about the search results page and the displayed
columns (i.e., this page).
By default, results are shown with 500 entries per page, with links
to additional pages if more than 500 entries were returned. The number of
rows per page can be modified using the "Records per Page" form element
on the search form. The total number
of entries returned is set by the "Maximum Records" value from the search page.
One numerical column can be plotted versus another using VOPlot
although see the Help page regarding issues
with the latest version of Java.
For some missions, thumbnail images of the returned entries
can be displayed by clicking the link listed just below the VOPlot link.
The mark column, as described below, can be used to plot spectra
and download files. Plots are now interactive with added features.
Mark this dataset for retrieval by pressing this checkbox.
After you have marked for retrieval all the datasets that you're interested in,
hit the Retrieve Marked Datasets for Retrieval button to initiate the retrieval.
Proprietary datasets will have a @ character next to their mark buttons
(and in some browsers will show up with a yellow background). Proprietary datasets
can be marked and retrieved by appropriately authorized users. If you are a principal
investigator and would like to retrieve your data (or would like to authorize one of
your co-investigators to retrieve your data), contact us at
archive@stsci.edu.
Users running Javascript-enabled browsers will see some buttons at the top and
bottom of the search results labelled Mark all, Unmark all, etc.
These buttons may be used to mark or unmark all of the datasets in the search
results; mark or unmark only the proprietary datasets; or mark or unmark only
the public datasets.
Name of an individual exposure within an observation set
(i.e., same as FITS header keyword ROOTNAME)
Also referred to as the Exposure ID on the exposure search form.
The Observation name is the unique identifier for a FUSE observation.
(For FUSE, an observation is an association of exposures.)
In the FUSE Observation search the Observation Name is the Data ID.
This is the same as the association ID also.
PINH (Pin hole - hasn't been used as of 9/24/2002)
RFPT Used either for instrumental test programs, or when
long background observations are made. The latter are tagged with
a target name, but since the target is at the reference point, its
light is not entering the spectrograph through one of the science
apertures.
exposure duration (seconds)--calculated
(Note this is different from the "Exposure time"
field which describes the total exposure time
for the entire observation.)
The FUSE instrument has a simple design with few observing modes.
The correct mode of observing is generally derived from the Phase 2 proposal
information (based on target flux and the desired S/N and spectral resolution)
for event rates < 2500 counts/sec (corresponding to a flat spectrum source
with flux of ~8 × 10-12 erg cm-2 sec-1 Å-1 in the LWRS aperture),
TTAG mode is the default observing mode. For rates higher than this,
spectral image (HIST) mode is used by default .
For more information see the
The FUSE Observer's Guide section on Observing Modes.
FUSE data has a nominal proprietary period of six months
(though in special cases, this may be shortened or extended). The
Release Date field gives the end of the dataset's proprietary period.
When the results of a search query are displayed, both public and
proprietary datasets will have mark buttons. Proprietary datasets will
have an at symbol, @, next to the mark button, and on most browsers,
the background for proprietary mark buttons will be yellow. Properly
authorized users will be able to retrieve proprietary data through the
Web interface.
