PVC/SKYRAD/M1 - Reprocess: Incorrect IRT Configuration

The SKYRAD IRT was installed temporarily (waiting for the new enclosure) in
a vertical orientation, without the use of the gold mirror. When irt_comm
was started, the emissivity parameter in the startup file was not changed to 1.000 
compensate for the absence of the mirror, resulting in a positive bias of about 5 K.

These data may be corrected by adjusting the radiance values for the difference in 
emmissivity.
