Effective Area: Recent Progress

UVIS C K-edge structure corrected for “wavelength offset”
Improved model CsI features based on lab & flight data
Problem region near 70 A demarking the regime between hot WD- and blazar-dominated calibration improved
Small (few %) revision < 6 A to match “new” (2000 cf 1999) extraction region efficiency
