HRC-I amp_sf correction and filtering comparison

Flat field images from the HRC-I laboratory calibration (June 1997) were reprocessed, making use of two routines for correcting the telemetered values of the crossed-grid charge detector amplifier scale factor (amp_sf). A detailed account of the need for this correction can be found in a memo by Mike Juda. The "fix 1" routine is based on an algorithm by Steve Murray, described in another memo by Mike Juda. The "fix 2" routine is based on Mike Juda's own algorithm. Status bit filters were then applied to the "fixed" event lists.
