Add to ORKGACIS observations of astronomical sources as well as its own external calibration source (ECS) have shown that molecular contamination has been building up on the optical/UV blocking filters since launch. Early LETG/ACIS observations of Ton S180 in Nov. 1999 and 3C 273 in Jan. 2000 showed that there was a slight reduction in the low energy ACIS QE1. A near
