B1s Trial 3D Flags
Revision as of 13:15, 24 May 2012 by Sstorm
- Requested 2 hour time reduction due to poor weather at start. (got them back)
c0924I.1D_88B1S.3 6.4 B+ Comments: NODE_NOT_FOUND [2012-05-07 09:07]AB+SC : Pretty good. C18 looks weird. A tsys spike around 00:30; weather isn't great during first part of track, improves after an hour.
csflag tsys=1500. select='time(19:40,21:30)' # bad weather at the beginning select='ant(3,4,5,6,7,8,9,10,11,13,14,15,22,23),time(00:29,00:40)' # high Tsys and high amp points * Gain cal fluxes seem to be overestimated due to the primary (Uranus) taken at the beginning in bad weather. So 19.2 Jy (3C84) and 3.2 Jy (3C111) from the previous tracks are assumed.
WIDE BAND csflag tsys=1500. # standard select='time(00:25:00,00:40:37.5)' #high amp select='time(19:46:00,21:09:46.5)' #poor weather; terrible phases NARROW BAND select='ant(18),win(1)' #noiser phases select='ant(22),win(1)' #noiser phases select='ant(22),win(4)' #noiser phases
csflag tsys=1500 select=ant(16,17,18,20,21),time(00:27:00,00:29:00) # 0 tsys select=ant(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,19,22,23),time(00:27:00,00:40:00) # high amp gains select=ant(2,3,4,5,6,15,19),time(20:15:00,20:30:00) # high amp gains select=ant(1,3,4,5,6),time(20:45:00,21:40:00) # high amp gains
1. When to stop flagging for bad weather? Katherine does not flag entire beginning chunk -- does specific flagging for high amp. 2. ~00:25 - 00:40 Shaye selects all bad, Woojin and Katherine select specific antennas 3. Katherine flags 0 tsys from 00:27-00:29 on select 3.5-m ants.
