Usage for lstrange

Return to directory of Todd's CASA extensions

Sometimes it is useful to know the LST range over which your ms was run. For example, this information is useful to the JAO data reduction scientist who can request a certain LST for the next execution of your SB. This command will do that, along with providing the UT and MJD and duration. The only parameter is the ms name. It will calculate the range for the entire ms, and then calculate the range restricted to the scans with ON_SOURCE intent (or other specified intent). It also lists the range of elevations ON_SOURCE, and a one-line summary that can be pasted into a table on the SCOPS wikipages.

Usage:

au.lstrange(vis, verbose=True, vm='', intent='OBSERVE_TARGET#ON_SOURCE')
Return values:
  • string, string, float, string: wikiline2, wikiline3, clockTimeMinutes, csvline
    • wikiline2: YYYY-MM-DD | SBuid | EBuid | HH:MM-H:MM | LST_HH:MM-HH:MM | clockTimeMinutes | '
    • wikiline3: ' elevationStart-elevationStop | ' (values in degrees)
    • csvline: SBuid,EBuid,clockTimeMinutes

Example:

CASA <16>: au.lstrange('uid___A002_X1465d3_Xc7.ms')
