v1_calculate_over_time

romancal.orientation.v1_calculate.v1_calculate_over_time(obsstart, obsend, **calc_wcs_from_time_kwargs)[source]

Calculate V1 over the given time period.

Returns a table of all V1 pointings that can be retrieved from the engineering database that exist between, inclusively, the start and end times.

The table has the following columns:

  • source (str): The string “time range”.

  • obstime (astropy.time.Time): The observation time.

  • v1 (float, float, float): 3-tuple or RA, dec, and position angle.

Parameters:

  • obsstart (float) – The MJD start and end time to search for pointings.

  • obsend (float) – The MJD start and end time to search for pointings.

  • **calc_wcs_from_time_kwargs (dict) – Keyword arguments to pass to calc_wcs_from_time.

Returns:

v1_table – Table of V1 pointing.

Return type:

astropy.table.Table
