scopesim_templates.misc.misc.point_source(sed, amplitude=None, filter_curve='V', x=0, y=0, ra=0, dec=0) → Source#

Create a point source with an arbitrary spectrum.

This is similar to scopesim_templates.stellar.star.

Parameters:

  • sed (str or synphot.Source_Spectrum) – Passing a str will try to download a sed from the speXtra database alternatively an user manipulated synphot.Source_Spectrum or compatible object can be provided.

  • amplitude (float) – flux or magnitude of the object. The SED will be scaled to that value if left to None (default) no scaling will be performed

  • filter_curve (str) – any astronomical filter in the speXtra or the spanish VO database

  • x (float) – X-coordinate on the plane in arcsec

  • y (float) – Y-coordinate on the plane in arcsec

  • ra (float, str) – RA coordinates of the center of the field (not used)

  • dec (float, str) – DEC coordinates of the center of the field (not used)

Returns:

src

Return type:

scopesim.Source
