NuSTAR pysolar API

nustar_pysolar.map.make_sunpy(evtdata, hdr, exp_time=0, on_time=0, norm_map=False, shevt_xy=<Quantity [0., 0.] arcsec>, ssw_legacy=False)

Make a sunpy map based on the NuSTAR data.

Parameters:

  • evtdata (FITS data structure) – This should be an hdu.data structure from a NuSTAR FITS file.

  • hdr (FITS header containing the astrometric information) –

  • keywords (Optional) –

  • exp_time (The exposure time (i.e. livetime, not on-time) no units.) – If not given then taken from hdr

  • on_time (The on-time (i.e. dwell) no units.) – If not given then taken from hdr

  • norm_map (Normalise the map data by the exposure time (i.e. livetime),) – giving map in units of DN/s. Defaults to “False” and units of DN

  • shevt_xy (2 element array of x and y shift to apply to) – evtdata before making the map (does to nearest pixel), defaults to [0,0], so no shift

  • ssw_legacy (Using evt converted to S/C via older sswidl code,) – which might need to specify CUNIT1 and CUNIT2. Defaults to “False”

Returns:

A sunpy map object

Return type:

nustar_map
