Skydips Method: Comparison Run5-Run6 results with ATM Model
Description
This is a comparison of the opacities derived with skydip technique between the run5 and run6. In Fig-1 we present the NIKA band-pass for the two NIKA channels together with the ATM model calculated for different water vapor contents. Note that the band-pass are different between run5 and run6, so we expect to have a different ratio between the opacities at 1mm and 2mm. In fig-2 we present the comparison between the opacities derived for 1mm and 2mm (blue point) channels and the ATM model (purple line). The left plots present the results for the run 5 and the right plots for run6. Note that for the run6 we have juste one point corresponding to the opacities derived from the skydip performed on June 11th 2013 scan number 159.
The agreement between the measure points and the ATM is good for both run5 and run6.
