Specifications for HST/GHRS Selections for Scrapbook
Permitted Observing Configurations:
Rank
Far-UV
Mid-UV
First choice:
G140L
G270M
Second:
G160M
Ech - B
Third:
G200M
Fourth:
G140M
Fifth:
Ech - A
Problems:
MINWAVE, MAXWAVE header keywords must be fixed for those datasets with
currently questionable values and which also contain *.c0, *.c1 files;
for those datasets wavelength limits taken from data files and will replace
the current erroneous ones.
Specifications for selected representative dataset:
Short- (<2000 Angstroms) and long-wavelength spectra will be displayed
for a given object whenever they both exist.
Low resolutions will have preference (as ranked below).
Select observation with the longest exposure time for a given grating configuration.
For two or more otherwise-equivalent observations, choose the observation first done.
Comments:
N.B.: Previews will be redone by CADC.
"GHRS Caveat": in case of observations existing at high-res for a target
nucleus, and low res nearby, pick the dataset for the target nucleus.
