This program calibrates MARCI images

Overview Parameters

Description

This program applies a flat-field correction for each framelet based on the band's filter number. In order to output in I/F units, the cube must have spice data. This calibration problem follows the algorithms described the document titled:

History

Steven Lambright2009-01-21 Original version
Steven Lambright2009-03-03 Added lookup table
Steven Lambright2009-04-09 Fixed a problem where segmentation faults would occur if run with the option "IOF=false"
Janet Barrett2014-07-01 Added code to obtain exposure times from $mro/calibration/marci/varexp.tab so they can be used when calibrating the input image. Also had to handle images that have been flipped by marci2isis. Fixes #1860.
Moses Milazzo2014-12-08 Fixed a bug in exposure time accounting. Fixes #1860.
Stuart Sides2019-11-08 Modified to use the exposure duration from the new label keywords added by marci2isis. Related #2034
Lauren Adoram-Kershner2022-07-15 Implimented step 3 of marci calibration description, where if normalized flatfile DN value is less than 0.25, the output cube DN is set to 0.
