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.

false

Returns
anyvariant

Example

    # get the times associated with scan number 10, all obsids, all arrayids.
