NICMOS Flanking Fields Observing Log

Logfile for the Hubble Deep Field South NICMOS Flanking Field observations. This listing contains basic information about the datasets, as well as a few useful "derived quantities" (e.g. an approximate measure of sky brightness, useful for screening out data with high background levels), and comments based on a preliminary visual inspection.


Note: The images have been named in such a way as to make the names more useful.

Image naming convention: prefixNN_VV_LLL

                prefix: flnk - flanking field

		NN:     flanking field ID (note that ff10 and ff11 are
                        the same field)

		VV:     not used

		LLL:    Exposure logsheet line number
                        from the proposal

The original suffixes have been retained. For each image there should be 6 files associated with it. They are:


*************************************************************************************************************
Image = Filename
Oldim = Original dataset name (in the archive)
UT_observed = Obs start time (DDD:HH:MM:SS 1998)
Daynum = Obs start time (UT decimal day)
Filt = Filter
Exp = Exposure time in seconds
Ns  = Number of samples
Sky = Mean "sky" background in DN/s
RMS = Sky rms in DN/s (excluding objects and vignetted region)
Xsh = X shift from reference image in pixels
Ysh = Y shift from reference image in pixels
Ori = rotation angle from reference image in degrees
Wt  = Weight used for final drizzled mosaic
USED = Image was used in final drizzled mosaic
A = Scattered light  -- Determined from plots of the first differences between imsets
B = SAA impacted (CR persistence) -- Flagged if occurred within 90min of SAA exit (Check image rms for significance)
C = Moving objects
D = Large cosmic ray hits
E = Bars (horizontal)
F = Bands (vertical)
G = Quadrant bias jumps
Comments = Data quality comments (CR=giant cosmic ray, MO=moving object, Number indicates in which read it occurred)
