The Farrel Lytle data is in the form of staps with calibration points. You need to make a conversion to energy. Grant Bunker sent me this description a while ago. I have written a Python program to do the conversion but have had no time to finish it off and make it really useful.
Much -- but not all -- of the data in the massive bitdump of measurements made by Farrel is in that form. This is a question that gets asked all the time on this list -- so much so that there is a FAQ on the topic. See question 3 at: http://cars9.uchicago.edu/iffwiki/FAQ/Data_Handling A way of converting the most common form of data in the Lytle bitdump is explained and could be easily implemented in many ways, including in a spreadsheet. The problem of weird data file formats and how Athena can deal with them is another topic that has been discussed at great length here and elsewhere. In fact, there is a whole section on the topic in the Athena User's Guide: http://cars9.uchicago.edu/~ravel/software/doc/Athena/html/import/plugin.html The information inthat link doesn't help Adhijeet import his data, but it does explain how Athena interacts with weird data files -- which is broadly useful information.
