For data users

Hello, I'm new to using the PDS node and I am struggling to open the .img files that I have downloaded. I'm able to view the .jp2 images associated with each data set, but not the .img files. I know that they are binary data files but I don't know how to access the data within them. Is there any way of getting them into an ASCII or other numerical based format, eg an x,y,(other variable) format? I'm hoping to analyse the data on a Linux system, so any advice tailored to Linux would be appreciated! Thank you very much, Sarah

Is there a table I could download that gives the MER position in local coordinates by either site number or Sol day? This information is implicitly available in the traverse maps of the Mosaic tool in the form of meters East and North of the landing site. I would like to be able to access this information in tabular form. Thanks, Bill

Hello, I would like to compare the data displayed in the LRO LOLA images (e.g. LDEM_80S_20M) to some other data and therefore I would like to use the same color scale. Can I download the color scale used in the LRO LOLA images anywhere on this site? Maybe in a format I'll be able to use in MATLAB? Regards, EBonacker

Hello, I'm new to using the MER Pancam products, and having trouble with the Spirit Sol 751 XYZ (and related) derived products. Loading into either MATLAB or ISIS, the XYL and related products seem to consiste almost entirely of zeros. Other products from Sprit Sol 751 (e.g. Pancam RSN) load fine and look sensible. Should I take this to mean that no useful range information was acquired that sol, or is there a workaround for getting range and XYZ information? Thanks, - Edwin
