But GSB power not equalized properly(tried 3 to 4 iteration). 08:35 : Changed power equalization script for GSB (ifpowereq to load_if_attn) and taken 3 iteration. 08:53 : GSB properly power equalized on 1822-096. 08:55 : \'/data1/gtac/cmd/bhaswati/39_063_06feb.py\' command file started. -------------------------------------------------------------------------- 09:55 : C06 taken for painting, so removed from GAC for GWB and C05 started working, so after phasing added in GAC for GWB. # GWB GAC configuration is as follows : # BEAM-1:130 :: C00 C01 C02 C04 C05 C08 C09 C10 C11 C12 C13 C14 E02 E03 E04 E05 E06 S01 S02 S03 S04 S06 W01 W02 W03 W04 W05 W06 Total=28 # BEAM-1:175 :: C00 C01 C02 C04 C05 C08 C09 C10 C11 C12 C13 C14 E02 E03 E04 E05 E06 S01 S02 S03 S04 S06 W01 W02 W03 W04 W05 W06 Total=28 # BEAM-2:130 :: C00 C01 C02 C04 C05 C08 C09 C10 C11 C12 C13 C14 E02 E03 E04 E05 S01 S02 S03 S04 W01 W02 W03 W04 W05 Total=25 # BEAM-2:175 :: C00 C01 C02 C04 C05 C08 C09 C10 C11 C12 C13 C14 E02 E03 E04 E05 S01 S02 S03 S04 W01 W02 W03 W04 W05 Total=25 -------------------------------------------------------------------------- 13:00 : Stopped command file and observing session over.
