class EXOSIMS.BackgroundSources.GalaxiesFaintStars.GalaxiesFaintStars(**specs)[source]

Bases: BackgroundSources

GalaxiesFaintStars class

This class calculates the total number background sources in number per square arcminute, including galaxies and faint stars.

dNbackground(coords, intDepths)[source]

Return total number counts per square arcmin

Parameters:

  • coords (astropy SkyCoord array) – SkyCoord object containing right ascension, declination, and distance to star of the planets of interest in units of deg, deg and pc

  • intDepths (float ndarray) – Integration depths equal to the planet magnitude (Vmag+dMag), i.e. the V magnitude of the dark hole to be produced for each target. Must be of same length as coords.

Returns:

Number densities of background sources for given targets in units of 1/arcmin2. Same length as inputs.

Return type:

dN (astropy Quantity array)
