Best-fit parameters and extrapolation of the fluxes in the NIKA bands of the radio sources in the 4 × 4 arcmin2 field around MACS J1423.8+2404.

Source RA offset Dec offset (arcsec) F 1 GHz α radio 150 GHz 260 GHz
[arcsec] [arcsec] [mJy] [mJy] [mJy]

RS1 0.3 2.6 10.39 ± 0.30 −0.548 ± 0.001 0.68 ± 0.08 0.54 ± 0.07
RS2 41.0 57.3 9.39 ± 0.69 −0.790 ± 0.003 0.18 ± 0.04 0.13 ± 0.03

Notes. The degeneracy between the slope αradio and the amplitude F1 GHz has been accounted for to extrapolate the flux in the NIKA bands. See text for details.
