Note: The following parameters are mission-specific.

CHANDRA:	Frame time (s) CHANDRA ACIS pile-up calculation only WebPIMMS ONLY uses the current Chandra Cycle data Use the CXC site to calculate prior Chandra Cycle data
IXPE:	To estimate the required exposure time enter the desired MDP99 (%)

WebPIMMS is a Web version of the PIMMS (v4.14) tool developed by Koji Mukai at the HEASARC. The first Web version was developed at the SAX Data Center. The SAX PIMMS package was ported to and modified for the HEASARC website by Michael Arida. Ed Sabol later rewrote and streamlined the code.
