NSA/MFR10M/C2  - Head temp out of tolerance

Beginning on 06/03, the 415 nm channel appears to be erratic or noisy at times, which does 
not coincide with the other channels.  Maintenance on 07/02 corrected this problem.

head_temp readings occasionally spike or are erratic, especially between 1500 and 2000 
UTC.  On 06/17, head_temp readings became ambient due to a bad signal cable connection.  
Maintenance on 07/02 ended this problem as well.

Due to the head_temp readings becoming largely out of tolerance, all channel readings 
should be considered questionable, especially after 06/17.
