The .evlist file is an RV format event list. See http://acis.mit.edu/ttools/acis-analysis.html for a description of the file format.
The .mca.data file is an IDL file created by the "save" command. The variables saved in this file are biasl, noise, evlog, peaknum, width, peakloc, bad_data, and good_data. biasl is an array that contains the frame number and the average overclock value for each of the four quadrants for each frame. noise is an array that contains the frame number, the standard deviation of the overclocks for each of the four quadrants, the total number of overclock pixels above the event threshold, the difference between pixels at the top of the image area and those at the bottom of the image area, and the difference between pixels in the image area and pixels in the overclocks for each frame. evlog is an array that contains the number of pixels above threshold, the total number of events, the number of g0234 events in all energies, and the number of g0 events in all energies for each frame. peaknum is an array that contains the total number of counts under the gaussian fit to the main peak of the cumulative g02346 spectrum for each quadrant for each frame. width is an array that contains the width of the gaussian fit to the main peak of the cumulative g02346 spectrum for each quadrant for each frame. peakloc is an array that contains the location in ADU of the gaussian fit to the main peak of the cumulative g02346 spectrum for each quadrant for each frame. bad_data is an array containing the frame number of all unacceptable frames (these frames are not included in the event list). good_data is an array containing the frame number of all acceptable frames.
The .mca.summary file is an ascii file that summarizes the data set. Included in the summary file are the thresholds used, the integration time (msec per frame), the total number of requested frames, the total number of acceptable frames, the total number of frames with unacceptable noise, the total number of frames with overclock pixels over the event threshold, the average overclock level, the average overclock standard deviation, the location (in ADU) of the fitted g02346 peak, the sigma (in ADU) of the fitted g02346 peak, the FWHM (in eV) of the fitted g02346 peak, the total number of counts in the fitted g02346 peak, the number of counts per frame in the fitted g02346 peak, a summary of the total number of events (all energies) in each grade, the branching ratios for each grade, and the counts per frame (all energies) for each grade for each quadrant.
The .mca.spec file is an IDL file created by the "save" command. The variables saved in this file are spectrum, uniplot, and badcol. spectrum is an array that contains the number of events per channel for each quadrant for each grade. uniplot is a 32 x 32 array of the uniformity of the g02346 events under the peak. Each value is the total number of g02346 events under the peak for a 32 x 32 pixel region (in chip coordinates). badcol is an array that contains the total number of events in the g02346 peak per column (in chip coordinates).
