*!!!!!!!!!!!!!!!!!!!!!!!!!!
* IMPORTANT: Again, as per Thomas' comment, verify your Video Converter setting since the values for your total LO
* as given in the $CODES section may be inaccurate.
*!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* CALIBRATION:   Procedures for Part 1 should be used.
* >>>>  Tsys should be measured before and after each VLBI scan (within POSTOB AND PREOB)   <<<<
* If this is not possible, please do regular Tsys measurements preferably BEFORE VLBI scans.
*
* If possible, please provide ANTENNA TEMPERATURE measurements and atmospheric OPACITY measurements
*
* Please send us an elevation dependent antenna GAIN CURVE and a value for its peak (e.g. in K/Jy).
*

*===========================================================================================
* PHASECAL (affects Pico Valeta, Haystack, Quabbin, Kitt Peak, Owens Valley):
*    For all VLBI scans except for the SgrA*/VX Sgr observations the Phase Calibration Tones 
*    should be ON.
*
*    For these 2 sources, phase cals may be reduced in amplitude or turned off, but
*    ensure phase cal is restored to normal amplitude after Sgr A section of schedule is
*    finished.    In case of doubt, leave phase cal unaltered for VX Sgr/Sgr A8, we will
*    live with it.
