pynrc.simul.ngNRC.sources_to_slope(source_table, nircam_obj, obs_params, tel_pointing, hdul_psfs=None, im_bg=None, cframe_out='sci', **kwargs)[source]

Create a slope image from a table or sources

Parameters

  • source_table (astropy Table) – Table of objects in across the region, including headers ‘ra’, ‘dec’, and object fluxes in NIRCam filter in vega mags where headers are labeled the filter name (e.g, ‘F444W’).

  • nircam_obj (pynrc.NIRCam) – NIRCam instrument class for PSF generation.

  • obs_params (dict) – Dictionary of parameters to populate DMS header. See create_obs_params in apt.py and level1b_data_model in dms.py.

  • tel_pointing (webbpsf_ext.jwst_point) – JWST telescope pointing information. Holds pointing coordinates and dither information for a given telescope visit.

  • hdul_psfs (HDUList) – Option to pass a pre-generated HDUList of PSFs across the field of view. If set to None, then generated automatically.

  • im_bg (None or ndarray) – Option to specify a pre-generated image (or single value) of the Zodiacal background emission. If not specified, then gets automatically generating.

  • cframe_out (str) – Desired output coordinate frame, either ‘sci’ or ‘det’

Keyword Arguments

  • npsf_per_full_fov (int) – Number of PSFs across one dimension of the instrument’s field of view. If a coronagraphic observation, then this is for the nominal coronagrahic field of view.

  • sptype (str) – Spectral type, such as ‘A0V’ or ‘K2III’.

  • wfe_drift (float) – Desired WFE drift value relative to default OPD.

  • osamp (int) – Sampling of output PSF relative to detector sampling. If hdul_psfs is specified, then the ‘OSAMP’ header keyword takes precedence.

  • use_coeff (bool) – If True, uses calc_psf_from_coeff, other WebbPSF’s built-in calc_psf. Coefficients are much faster
