Version v1.2.0 (Tue Sep 27 21:08:13 2022)-------------------------------------------

 * Added VIIRS RSR for JPSS-2/NOAA-21:   Based on the J2_VIIRS_RSR_DAWG_At-Launch_Public_Release_V2_Jul2019.zip   The data read are the Detector wise files under J2_VIIRS_Detector_RSR_V2:

   J2_VIIRS_RSR_DNBLGS_Detector_Fused_V2FS.txt   J2_VIIRS_RSR_I1_Detector_Fused_V2F.txt   J2_VIIRS_RSR_I2_Detector_Fused_V2F.txt   J2_VIIRS_RSR_I3_Detector_Fused_V2F.txt   J2_VIIRS_RSR_I4_Detector_V2F.txt   J2_VIIRS_RSR_I5_Detector_V2F.txt   J2_VIIRS_RSR_M10_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M11_Detector_V2F.txt   J2_VIIRS_RSR_M12_Detector_V2F.txt   J2_VIIRS_RSR_M13_Detector_V2F.txt   J2_VIIRS_RSR_M14_Detector_V2F.txt   J2_VIIRS_RSR_M15_Detector_V2F.txt   J2_VIIRS_RSR_M16A_Detector_V2F.txt   J2_VIIRS_RSR_M1_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M2_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M3_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M4_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M5_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M6_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M7_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M8_Detector_Fused_V2F.txt   J2_VIIRS_RSR_M9_Detector_WVCOR_Fused_V2F.txt

   The two files here were not considered:   J2_VIIRS_RSR_DNBMGS_Detector_Fused_V2FS.txt   J2_VIIRS_RSR_M16B_Detector_V2F.txt

 * Correted errors concerning NOAA-6 channel 1 and 2. These proved to be wrong   (a factor of 10 scale error), as the files they were based on were   wrong. For AVHRR-1 we have been using the ascii files from NOAA STAR   (https://www.star.nesdis.noaa.gov/smcd/spb/fwu/homepage/AVHRR/spec_resp_func/index.html). Example   of the start of the file for NOAA-6 channel-1:

   %> cat NOAA_6_A103C001.txt      Wavelegth (nm)      Normalized RSF         5600.000000            0.071000         5700.000000            0.449000         5800.000000            0.739000         5900.000000            0.813000         6000.000000            0.806000         6200.000000            0.919000         6400.000000            1.000000         ...

   Here we have instead used the xls files on which the NOAA-STAR files are based: AVHRR1_SRF_only.xls

   For TIROS-N there seem to be a typo in the wavelengths array for channel-1   on TIROS-N: A 640 nm should most likely have been 840 nm. This has been   corrected in the hdf5 file.
