Cross and Focus analysis
FXD 4-Sept-2012
Back to the offline processing of NIKA run 4
Here we show some results on the cross and focus scans. We use the focal plane reconstruction by NP on the last scan of the run #168_20120604 in order to go further than simply analyzing one kid at a time.
Crosses on Mars
For example, one can remove/mask common glitches. One can also remove a common mode (obtained by summing all detector timelines after masking the source). Here are some examples on one scan:
The (faint) line is a simple Gaussian fit with a linear baseline which goes along nicely to the data points. The parameters of the fit are written on the plots and show 12 arcseconds at 1 mm. One can also construct a film of the Mars crossing
