 # Rotate the FITS image to be upright using 'dmregrid2',
-# and crop the outside blank areas of the rotated image
-# according to the CCD sizes.
+# and crop the blank edges from the rotated image
+# according to the CCDs sizes.

 # NOTE:
-# * rotation angle is obtained from "ROLL_PNT" keyword
-# * rotation center is the central point of the input image
-#   (in _image_ coordinate and in pixel unit)
-# * cropped image size is set to '1204x1204' for ACIS-S, and
-#   '2066x2066' for ACIS-I
+# * rotation center is set to be the center of the input image
