  1. I first wanted to say how impressed I have been by all of the support material and software for CRISM. I really appreciate all of the hard work that everyone has done, especially as a new user. My question regards the bad bands list. I have been following the Nilli Fossae walkthrough while processing a set of data from Ganges Mensa. The processing works well until the step where I clean the spectral cubes. The first time that I tried processing a cube, the software failed. I determined that there were some bands that had a lot of values of 65535 throughout the image and not just on the left side. By editing the bad bands list to exclude these bands, I can get the despising and destriping to run. I have noticed that I have to make sure to get rid of every "bad" band because, if there are a couple still in there, the clean can produce ringing in the spectrum. However, since I am using the NIR from bands 4-254, I have started trimming off the rest to save space and time. My questions is this: does trimming off the wavelength affect the destriping and despiking? Do I have to use the entire wavelength range for it to work properly, or does it not matter? I have been editing the header in the original CAT file so that all of the corrections are on the same bands. Please let me know if change the wavelength range changes any of the other programs as well. Thanks in advance for your help! I can provide images and examples of what I am talking about if needed. Best Wishes, Rachel Mastrapa
