  1. Hi, I understand that using CAT ENVI tool we can do ATP correction to an CRISM image by selecting a single image file each time. However, I need to use ATP correction for thousands of CRISM images. Just wondering if there is any way I can run batch ATP process multiple images without needing to select a single image at each time? Thank you, Emran
  2. Hi, I need some help to understand the data processing of CRISM data (TRR3). I use CAT tool coupled with ENVI 5.3. I use CAT manual (workshop manual available in the website) for the processing which goes as Conversion of PDS to CAT--> Photographic and Atmospheric Correction--> Georeferencing. I observe that after the atmosphere correction spectra do not change much but once perform the geometric correction it shows changes as shown in the figure. Is obtained result correct? What is the main reason for this change? I would also like to know how to obtain ratioed spectra. I am familiar with spectra ratios but my confusion is how to choose spectra (denominator) which does not introduce errors, what region' pixels would be a better choice? Is atmospherically corrected spectrum same as I/F spectrum? All plots are atmospheric corrected. Thanks,
