Compare 20240409 demodulation matrices to temperature dependent fit

mgalloy commented 7 months ago

Tasks

[x] compute demodulation matrix for 20240409 for each wave region
[x] compare to temperature dependent fit from existing demodulation matrices in pipeline
[x] use UCoMP_Pol_Cal_Temperature.pro to plot 16 coefficients vs temperature, indicating prominently the 20240330 polarimetric calibration data on it

I ran ucomp_pol_cal.pro from Steve on 20240409, which gave demodulation matrices for the following wavelengths, at the given temperatures:

Wavelength	Unfiltered Temperature
637.400	33.0900

Above are the demodulation matrices for the calibration data taken during October 2022, along with the percentage difference from the fit. Just looking at the results, it seems that large percentage difference (say > than 8%), mostly correspond to small coefficients (say < 0.07).

mgalloy commented 6 months ago

@bberkeyU I've added the plots task with UCoMP_Pol_Cal_Temperature.pro to this issue. Are you still interested in doing that?

bberkeyU commented 6 months ago

@mgalloy I started looking at this in IDL, but I hit an issue: I dont know how to set colors in IDL with Steves's post-script code.

I tried messing with the color tables (loadct) and trying various options for oplot....color=[various numbers between 0-255], but I am only getting black points.

Reading the sav files in Python, I get the following plots: The red star is created with the following values:

I made plots for 637, 789, and 1079 in this studies notebook. https://github.com/NCAR/ucomp-studies/blob/master/demodulation/Plot%20UCoMP%20demodulation%20vs%20temp%20with%20new%202024%20data.ipynb

detoma commented 6 months ago

The new polarimetric calibration is not consistent with the old ones for 1074 and 1079. There is nothing we can do to test this further because the observatory is closed. We need to be revisit this when we reopen and test if this calibration was an outlier or if something in the instrument has changed.

For the processing of the March-April 2024 we will use the old function based on the data taken throughout the mission until November 2022.
