The current multibeam reader assumes that sc_ant is set to the number of beams plus 1, and that the beams (ants) are written out in order with antenna 0 last. Is that right? >There are also extra quantities written for each antenna: >c >c QUANTITY 15: Calibration signal size in Jy - pol A >c QUANTITY 16: Calibration signal size in Jy - pol B >c QUANTITY 17: Total power counts - cal off - pol A >c QUANTITY 18: Total power counts - cal on - pol B >c QUANTITY 19: Total power counts - cal off - pol A >c QUANTITY 20: Total power counts - cal on - pol B >c The RPFITS definition gives element 1: antenna number (points to AN table) element 2: IF number (points to IF table) element 3: X-Y phase in radians element 4: sqrt(Tsys) of X in K**0.5 element 5: sqrt(Tsys) of Y in K**0.5 elements 6-8: sampler statistics for X elements 9-11: sampler statistics for Y element 12: flag (0 is good, otherwise is bad) element 13: X-Y amplitude Is element 14 the "on-source" flag?
