astscript-sort-by-night - Sort input FITS files by night
astscript-sort-by-night [
OPTION]
FITS-files
This script is part of GNU Astronomy Utilities 0.19.
This script will look into a HDU/extension for a header keyword in the given
FITS files and interpret the value as a date. The inputs will be separated by
"night"s. The definition a "nights" is set with the
'--hour' option (just note that the FITS time may be recorded in UTC, not
local time)! It will then print a list of all the input files along with the
following two columns: night number and file number in that night (sorted by
time). With '--link' a symbolic link (one for each input) will be made with
names including the night classifier. With '--copy' instead of a link, a copy
of the inputs will be made.
For more information, please run any of the following commands. In particular
the first contains a very comprehensive explanation of this script's
invocation: expected input(s), output(s), and a full description of all the
options.
