NSA/SKYRAD/C1 - reprocess: PIR identified as unshaded is really shaded

On 5/15/02 the Global PIR was moved from the unshaded
position on the Skyrad stand to a shaded spot on
the tracker.  It is still using the same Logger
channel as it did as an unshaded PIR even though it
is now shaded.

NSA/SKYRAD - Barrow SKYRAD PIRD Misconfiguration 12/9 - 12/12/98

The PIRD was incorrectly set from 12/9/98 to 12/12/98 that resulted in an 
error of approximately 3.7% (was set to 243902 instead of 235294).

NSA/SKYRAD/C1 - Incorrect 20s dome thermistor data

The 30-second and 50-second PIR2 diffuse dome thermistor data
in all skyrad 20s data records taken to data is in fact case
thermistor data.  No other data are affected.  The 20 second
skyrad data cannot be used to recompute the diffuse PIR2 data.

Note: This data was named pir2_dome_therm at the beginning of
this time range andlater the variable was renamed to
inst_down_lng_shaded2_dome_resist.
