 .Using Jack-Knives maps, we are able to estimate the noise level in the data.

Brief analysis of the faint source HLS091828 (z=5.243)

Coordinates:

  • R.A. = 09h18m28.6s
  • Dec. = 51d42'23.3"

Expected luxes (Combes et al. 2012):

  • F1.3sma= 55+-7mJy
  • F0.88mm= 125+-8mJy
  • F2mm= 15+-7mJy

NIKA obsevations:

  • Day: 13/06/2013

  • Scans: 9 Lissajous of 5 min each with followed by tracks (for tuning), 180 to 197

  • Size of the map:90"x90"

  • We detect the source at both wavelenghts, shown on the maps given bellow.

  • The profiles are computed by averaging the map in concentric annuli, and we check that the measured flux is, a priori, consistent with what we expect.

  • The time per pixel maps are also shown
