From 0b70d419a58eab46e39157b1f4c079a5984ab4ff Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?H=2E=20Moritz=20G=C3=BCnther?= Date: Tue, 21 Nov 2023 12:33:45 -0500 Subject: [PATCH] Change dither defaults to current Chandra ACIS Starting in cycle 25, Chandra moved to a larger dither pattern for ACIS by default. This changes the defaults in marx.par to match those ACIS patterns.
