XRT irradiance study --- part 3 ---
18-May-2020, Aki Takeda.
1. Effect of the various corrections to the irradiance study
1.1 Contamintion spot correction
Corrections performed in composite image processing through
xrt_spotcor.pro and eclipse_spotcor.pro using
spot and dust maps.
1.2 Stray light correction
1.3 CCD bakeout (growth of the contamination layers)
Growth cureve of CCD contamination layer
1.4 XRT response modified by the stray light contamination
Anomalous Ti_poly/Al_mesh filter ratio curve found for Jan-2008.
2. Soft-X-ray Solar Minimum
