Source Region Per-Stack Detections Tri-Color Image Files (regimg3.jpg)

The per-stack detections ACIS tri-color image JPEG file takes the bundle of background-subtracted, exposure-corrected source (either point source or CHS source) region images, combining by source detection energy bands and assigning each band to a separate JPEG color channel: soft (red), medium (green), and hard (blue). The boundaries of the JPEG images are the per-stack detection regions for the compact sources, and the bounding box around the master hull region for the convex hulls.

The stacked observations tri-color image JPEG file is named: 〈i〉〈s〉〈stkpos〉_〈stkver〉N〈v〉_〈r〉_regimg3.jpg

where 〈i〉 is the instrument designation; 〈s〉 is the data source; 〈stkpos〉 is the position component of the stack name, formatted as "Jhhmmsss{p|m}ddmmss"; 〈stkver〉 is the 3-digit version component of the stack name, formatted with leading zeros; 〈v〉 is the data product version number; and 〈r〉 is the region ID, formatted as "rnnnn", where nnnn is the 4-digit region number, formatted with leading zeros.
