v1_calculate_over_time

jwst.lib.v1_calculate.v1_calculate_over_time(obsstart, obsend, siaf_path=None, **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.

  • siaf_path (None or file-like) – The path to the SIAF database. If none, the default used by the pysiaf package is used. See SiafDb for more information.

  • 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
