3 - Photometry

Evolution of the sky opacity during Run#3

Absolute photometry

Using pointing sources (mostly quasars), we compare the absolute flux measured with NIKA run3 with an estimate obtained using PdB measurements. The summary of the photometry is given here as a spreadsheet and in this figure:

The agreement is reasonable with the fluxes covering from 1.5 to 15 Jy.

4 - Focal Plane Geometry and Beams

Both RZ (Mopsic) and NP (IDL, from This pdf) have found a distortion of the focal plane geometry well beyond the expected one.

The focal plane distortion affects the beams in a correlated fashion with the Focal Plane Geometry distortion. This points towards a general optical distortion common to both detectors (an optical element is misplaced in the optical train).

5 - Glitches

4 examples of glitches as seen by all detectors, 2 on the A array and 2 on the B array. (Scan 64, A665, 20111020)

Glitch on A, Another glitch on A

Glitch on B, Another glitch on B (quite strong)

6 - Mars plateau
