Comments (During Observations) : 07:00 : Started settings. 07:10 : Started power eq @ 250 counts. 07:20 : Started phasing on 3C48. # GSB GAC configuration is as follows : # BEAM-1:130 :: C00 C01 C03 C04 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 E04 E05 E06 S01 S02 S03 S04 S06 W01 W03 W04 W05 W06 Total=27 # BEAM-1:175 :: C00 C01 C03 C04 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 E04 E05 E06 S01 S02 S03 S04 S06 W01 W03 W04 W05 W06 Total=27 # BEAM-2:130 :: C00 C01 C03 C04 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 S01 S02 W01 Total=17 # BEAM-2:175 :: C00 C01 C03 C04 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 S01 S02 W01 Total=17 07:28 : Started phasing on 1822-096. 07:40 : Started command file. 08:20 : Noticed that for the source 1940-24 antennas were tracking at +24 deg declination instead of -24 dec declination, then I searched though source file and found that there was problem in reading coordinates.(RA was not correct) in /odisk/gtac/cmd/32_075/src.list which is the path mentioned in command file. Now coordinates are corrected, but the source has set for today. 09:12 : C04 servo problem. Removed from GAC. # Udated GSB GAC configuration is as follows : # BEAM-1:130 :: C00 C01 C03 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 E04 E05 E06 S01 S02 S03 S04 S06 W01 W03 W04 W05 W06 Total=26 # BEAM-1:175 :: C00 C01 C03 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 E04 E05 E06 S01 S02 S03 S04 S06 W01 W03 W04 W05 W06 Total=26 # BEAM-2:130 :: C00 C01 C03 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 S01 S02 W01 Total=16 # BEAM-2:175 :: C00 C01 C03 C05 C06 C08 C09 C10 C11 C12 C13 E02 E03 S01 S02 W01 Total=16 09:40 : Stopped observations.
