+Radiometric 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).
+
+Additionally, 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:
