WebPIMMS is a Web version of the PIMMS (v4.14) tool. PIMMS was 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.
