HELP SECTION
FXTIM
Task: This task will read a uv data set to find the lowest time. If
that is less than zero, it will change the start date and adjust
all times while copying the data.
Adverbs:
INNAME.....Input UV file name (name). Standard defaults.
INCLASS....Input UV file name (class). Standard defaults.
INSEQ......Input UV file name (seq. #). 0 => highest.
INDISK.....Disk drive # of input UV file. 0 => any.
OUTNAME....Output UV file name (name). Standard defaults.
OUTCLASS...Output UV file name (class). Standard defaults.
OUTSEQ.....Output UV file name (seq. #). 0 => highest unique
OUTDISK....Disk drive # of output UV file. 0 => highest with
space for the file.
REFDATE....Desired reference date 'yyyymmdd' ('dd/mm/yy' accepted
but deprecated), ' ' => header value
The minimum of REFDATE (wrt header date) and the minimum
time in the data set wrt header date will be used to set
a new date.
FQCENTER...> 0 => Change frequency axis reference pixel to
Nchan / 2 + 1
