Hello Everyone, I have a very large number of data files (>10,000) that I'm trying to average using Ifeffit. However, I'm having trouble coming up with the energy scale for the averaged file. The energy scale for each individual file is very similar, but not identical, so I'm not sure if it is the best idea to use the energy scale of a single file as the energy scale for the averaged file. I'm sure that I'm not the first person to deal with this problem, so I'm interested to hear how other people deal with this problem. I'm also sure that Bruce has already come up with a clever way of dealing with this problem in Athena, but unfortunately loading 50 files at a time into Athena to average is a too slow a process. So I'd rather do them 50 at a time from the command line.
