Next: Model Spectra for Spectral-Fitting Up: Spectral Analysis Previous: A Quick Look at . ... For ROSAT PSPC data, this conversion is done during the on-line (SASS) processing. For IPC observations, the instrument gain varies both across the detector and in time, and is applied during off-line processing (PROS) using the BAL histogram. By default, spectra are extracted in PI bins for PSPC data and in PHA bins for IPC data. ... Special techniques are required when using Einstein IPC data. ...

... If you have a program to convert data to MIDAS input format, fine. ... All you need to do is cannibalize the part of the existing program that reads the data, and add a short piece of code to re-format the data first as a flat ASCII file, one measurement per line; and then convert this to *.tbl format. ... It's just like the process of creating a program-star table. ...
