	Comments:  opt 1 at record 500 shows video min > BB counts; BB range, gain, video range ok; head counts = BB counts for channels
		   1-25. 
		   Channel 49 appears to have a LN2 blowoff; masprint opt 1 reveals a corresponding BB range > 100 counts. 
		   Vertical profile (envi) of ch 49, sample 723, reveals an anomaly from record 50730-51470. Rest of profile appears
		   nominal.
