MTA ACIS Corner Pixels

The links below show plots of average corner pixel centroid slope and mean for ACIS observations. Separate plots are shown for FAINT MODE (3X3) and VFAINT MODE (5X5) observations.

Metric is the centroid of a gaussian fit to the histogram of corner pixel PHA values of detected events.

Corner pixels are defined as:

FAINT VFAINT AFAINT
(3X3) event island  (5X5) event island (5X5) event island
(1,1)-----(1,3)
-----* -----
(3,1)-----(3,3)
  
(1,1)(1,2)(1,3)(1,4)(1,5)
