Archiving spectral line data at AO

Input and process a set of position switched data.

• Read and process all 232 position switched patterns for a1199
• 2048 channels, 4 sbc, 6 sec integration, 70 recs/scan, about 1gByte of data.
• input posOn, hanning smooth, avg
• input posOff, hanning smooth, avg
• input calon,off and compute scaling factor counts to Kelvins
• lookup gain curve to scale Kelvins to Jy
• compute PosOn/posOff - 1
• convert fraction Tsys to Jy with scaling factors, 0 lag.

214 processed onoff pairs returned, 18 pairs had different data format.
It took 4 minutes to input and process the data.

Plot the 2nd onoff pair ( the first was a continuum source).
