Usage for dateStringToMJDSec
Return to directory of Todd's CASA extensions
This function converts a date string into MJD seconds. This value is useful for passing time ranges to
plotms, because they must be specified in mjd seconds (see
CAS-3270). See also
dateStringToMJD and
strDate2MJD.
Usage:
au.dateStringToMJDSec(datestring='2011/10/15 05:00:00', datestring2='', verbose=True, use_metool=True)
- Any of these formats is valid:
- 2011/10/15 05:00:00 or 2011-10-15 05:00:00
- 2011/10/15-05:00:00 or 2011-10-15-05:00:00
- 2011/10/15T05:00:00 or 2011-10-15T05:00:00 or 2011-Oct-15 05:00:00
- The time portion is optional.
- If a second string is given, both values will be converted and a string will be created that can be used as a plotrange in plotms.
- Returns the value in seconds.
- use_metool: if True, use the casa measures tool; otherwise use a acanned formula for converting to MJD
Example:
CASA <8>: au.dateStringToMJDSec('2011/10/15 05:10:54','2011/10/15 05:11:54')
MJD= 55849.21590, MJDseconds = 4825372254.0
plotrange = [4825372254.0, 4825372314.0, 0, 0]
Out[8]: [4825372254.0, 4825372314.0]
