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, obsendfloat

The MJD start and end time to search for pointings.

siaf_pathNone 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_kwargsdict

Keyword arguments to pass to calc_wcs_from_time.

Returns:
