VizieR Online Data Catalog: NIKA Sunyaev-Zel'dovich data release (Adam+, 2018)
Abstract
The surface brightness maps of the 6 clusters obtained with NIKA at the IRAM 30-meter telescope at 150 GHz are presented together with the necessary data products to use them. They were obtained between November 2012 and February 2015. In the case of the cluster RX J1347.5-1145, the map can only be used qualitatively and the extra data products do not apply. The 150GHz bandpass is provided. The maps FWHM angular resolution is 18.2" and we provide the beam profile. Due to the scanning strategy, the noise rms is relatively constant in the central 80" radius but rapidly increase towards the edge. Noise Monte Carlo realization are provided to address the noise properties. Scales larger than 2' are filtered during the data reduction and the corresponding transfer functions are is provided. The clusters fields are contaminated by point sources and we provide best-fit point source models. The cluster MACS J0717.5+3745 is affected by kinetic SZ signal and we provide a best-fit model to correct for it. The image coordinates can be found in the FITS header. Units are mJy/beam.
