scopesim_templates.misc.misc.source_from_array(arr, sed, pixel_scale, amplitude, filter_curve, ra=0, dec=0) → Source#

Create a source from an image (numpy 2D array).

Parameters:

  • arr (np.ndarray) – a 2D numpy array

  • sed (basestring) – any sed available in the spextra library or a Spextrum object

  • pixel_scale (float, u.Quantity) – pixel scale on the sky (u.arcsec, u.arcmin, u.deg).

  • amplitude (float, u.Quantity) – magnitude of the spectra in a filter_curve

  • filter_curve (basestring) – a filter in the speXtra database or the SVO

Returns:

src

Return type:

scopesim.Source
