     3Calibration files are produced by Specim when they do maintenance on the instrument.

     6Files look like:
     7 SN100022_130207_XB.cfg::
     8   Lens configuration file - contains calibration date and a few other human-readable items
     9 SN100022_130207_XB.hdr::
     10   Header file for the data file..
     11 SN100022_130207_XB.cal::
     12   Data file (containing several frames?) of the per-pixel calibrations

     26Radiometric calibration done by <name of guy> at Environment Agency (or Met Office?).  Consists of five 700KB files named inXXaA.rad, where X = two digit calibration sequence (up to 36 for 2007) and A = aperature (1-5).
     27
     28Additionally, there is a file that describes the view angles for each pixel to compensate for (lens?) distortions in the view field.  The current version of this file is named NERC253_527tan.txt and looks like:
