Help for TIMSCAL
PURPOSE:
TIMSCAL is a program which calibrates TIMS data which have already been
logged with the program TIMSLOG. It can output two types of data, instrument
perceived radiance (IRAD), or instrument perceived temperature (ITEM). The
output is a data set of all six bands in two byte integer.
EXECUTION:
The following is the execution statement format for TIMSCAL:
TIMSCAL INP=(PIX,AUX) OUT=CALPIX PARAMS
where INP, OUT, and PARAMS are parameters discussed in their res-
pective parameter sections.
OPERATION:
TIMSCAL takes two input data sets - the first is a TIMS image file and the
second an auxiliary file for calibration, both of which are output from TAE
program TIMSLOG. Based upon the auxiliary file, it calibrates a TIMS image
(6 bands), according to the type of data specified with keyword CALMODE.
The units output for radiance images are milliwatts/m**2/um/sr. The units
output for temperature images are in hundredths of degrees Celsius. Output
is in halfword (two byte signed integer) format.
