timeOnSourceSD
Return to directory of Todd's CASA extensions
Determine the time spent on-source and off-source (per-antenna, and sum) for single-dish datasets. See also
timeOnSource.
Usage:
au.timeOnSource(vis, obsid=0, spw=None, debug=False)
- spw: which spw to use to analyze times. default=None=first non-WVR science spw
- Returns:
- the total on-source time in minutes
Example:
CASA <2>: au.timeOnSourceSD('uid___A002_X6de43a_X14e9.ms')
There are 42380 rows and 1 OBSERVATION_IDs in this dataset = [0]
spws with observe_target = [ 0 17 18 19 20 21 22 23 24]
Choosing spw=17
3300 rows have spw=17
PM01: 714 rows have spw=17 and an off_source state id (percent flagged=0.000)
PM01: 714 rows have spw=17 and an on_source state id (percent flagged=0.004)
PM01: on source time = 907.2 sec = 15.1 min
PM01: off source time = 719.7 sec = 12.0 min
PM04: 714 rows have spw=17 and an off_source state id (percent flagged=0.000)
PM04: 714 rows have spw=17 and an on_source state id (percent flagged=0.004)
PM04: on source time = 907.2 sec = 15.1 min
PM04: off source time = 719.7 sec = 12.0 min
sum of 2 antennas:
on source time = 1814.3 sec = 30.2 min
off source time = 1439.4 sec = 24.0 min
on-source efficiency = 32.2%
