PPT-Effective Stray Light Correction for EUV Images

Paul Shearer with Richard A Frazin Anna C Gilbert and Alfred O Hero III The Stray Light Problem Stray light for this talk the long range scattering component of the PSF Stray light makes bright features dimmer dim features MUCH brighter hindering quantitative science. Stray voltage can be found in any electrical system and is strictly a power distribution issue improper grounding causes low voltage current to travel along a neutral wire An electrical wiring system is grounded in order to keep voltage potential di What is Stray Voltage Types of Voltage Sources The two children play with him all afternoon but the family leaves him at the park because they think the might hav e an owner All week they cant stop thinking about him and when they return to the park on Saturday what they find will surprise reade February 7, 2013.
