marcical
This program calibrates MARCI images
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 Lambright | 2009-01-21 | Original version |
| Steven Lambright | 2009-03-03 | Added lookup table |
| Steven Lambright | 2009-04-09 | Fixed a problem where segmentation faults would occur if run with the option "IOF=false" |
| Janet Barrett | 2014-07-01 | 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 Milazzo | 2014-12-08 | Fixed a bug in exposure time accounting. Fixes #1860. |
| Stuart Sides | 2019-11-08 | Modified to use the exposure duration from the new label keywords added by marci2isis. Related #2034 |
| Lauren Adoram-Kershner | 2022-07-15 | 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. |
