Tidbinbilla notes for VT02f5 and V181e

Config notes

  • Centre freq = 2268 MHz
  • Polarisation = RCP
  • 1st LO = 2000 MHz
  • mix to 160 MHz into DAS
  • so 2nd LO for USB mix = 2268 - 2000 + 160 = 428 MHz
  • DAS profile = vsop_f.pro
  • receiver config RCP → LNA2 (low noise path) → out (output 1 for SNT monitoring). So `SRLA2O1

sidereal_apc input file

  • in cc@nmc-wsN:$NMCOPSBLOCKDIR/conn/hostRA/sked_files
  • File name should be sched_daynumber_antenna e.g sched_070_43
  • Format:

028:20:55:00 200116.6 -174808 300.3195 -17.8023 OV-198 ddd:hh:mm:ss HHmmss.s DDmmss RA_deg Dec_deg Name

  • Note that sidereal_apc uses RA_deg and Dec_deg, ignores sexigesimal formated columns
  • Ra and Dec must be in geocentric apparent coordinates
