+ | * "source" commands for APOD scans deleted in snp file (tracking is handled independent from the FS vis AzEl files) | ||
+ | * No possibility to disable pCal tones just for the APOD scans. pCal tones will still cover two DOR tones (however, due to the symmetric arrangement of the DOR tones the influence on the delay resolution function should be small) | ||
+ | * First APOD block (a332a): All three antennas were tracking and recording. S band amplitudes on SA quite stable. Large periodic amplitude variations in X band (narrower beam). | ||
+ | * APOD was tracked successfully in 2nd and 3rd sat. block (a332b and a332c). | ||
+ | * Good amplitude stability in a332c | ||
+ | * Due to maintenance work at the maser, the session had to be ended 1 hour earlier. The 10 min scan on the calibrator src was shifted. | ||
