############################

This catalog includes point sources that were added to the CEERS NIRCam imaging simulations. Mirage adds real point sources with magnitudes V<16 based on RA,Dec from 2MASS, WISE, and Gaia. We added fainter point sources (16 < V < 29) using the Besancon Model to approximate the correct stellar density and luminosity distribution in the EGS field.

The catalog is available as an ASCII table (ptsrc.cat).

The catalog contains the following columns:
    id             n/a              running ID number
    ra             [degree]         ra positions in sky
    dec            [degree]         dec positions in sky
    NIRCam_F115W   [Vega mag]
    NIRCam_F150W   [Vega mag]
    NIRCam_F200W   [Vega mag]
    NIRCam_F277W   [Vega mag]
    NIRCam_F356W   [Vega mag]
    NIRCam_F410M   [Vega mag]
    NIRCam_F444W   [Vega mag]
