msmetadata.timesforscan - Function

1.3.2 Get the unique times for the specified scan number, observation ID, and array ID.

Description

Get the unique times for the specified scan number, observation ID, and array ID. If perspw=True, the returned data structure is a dictionary that has keys representing zero-based spectral window IDs and values representing the unique values of the TIME column corrsponding to the specified scan and that corresponding spectral window ID. If False, an array of unique values from the TIME column for the specified scan is returned; there is no separation into spectral window IDs.

Arguments


Inputs
scan	Scan number for which to return the times.
	allowed:	int
	Default:	-1
obsid	Observation ID. A negative value indicates all observation IDs should be used.
	allowed:	int
	Default:	-1
arrayid	Array ID. A negative value indicates all array IDs should be used.
	allowed:	int
	Default:	-1
perspw	Return output dictionary with keys representing spectral window IDs (True), or an array of all times (False).
	allowed:	bool
	Default:	false

Returns
anyvariant

Example

    msmd.open("my.ms")
    # get the times associated with scan number 10, all obsids, all arrayids.
    times = msmd.timesforscans(10)
    msmd.done()
