From roban@sccs.swarthmore.edu Tue Aug 14 10:56:03 2001 Date: Tue, 31 Jul 2001 16:36:48 -0400 (EDT) From: Roban Hultman Kramer To: Tbalonek@mail.colgate.edu Cc: Jay.M.Pasachoff@williams.edu, Stephan E. Martin Subject: Re: Roper Scientific / Princeton Instruments SPE headers Hi, I am a Swarthmore student doing a Keck fellowship at Williams this summer. I'm working on the experiment that used the VersArray with WinView and spent some time wrestling with the headers, as well. My notes on what I've done, along with the sample files and header info you wanted are available here: http://www.sccs.swarthmore.edu/~roban/temperature/conversion/conversion.html I'd like to talk with you more about what problems you've encountered in your own efforts. It sounds like you've already achieved much more generality than I have at this point. Let me know if I can do any more to help. -Roban Hultman Kramer Swarthmore 2003 Astrophysics On Tue, 31 Jul 2001 Jay.M.Pasachoff@williams.edu wrote: > > ------- Forwarded Message > > Return-Path: Tbalonek@mail.colgate.edu > Subject: FW: Roper Scientific / Princeton Instruments SPE headers > To: "'Kwitter, Karen'" , > "'Pasachoff, Jay'" > Message-id: <01020B7EC4B7D311BE2E00508B6F7C1C029CD1EF@MAILSV06> > MIME-version: 1.0 > X-Mailer: Internet Mail Service (5.5.2650.21) > Content-type: text/plain; charset="iso-8859-1" > > Jay and Karen, > I sent this to Steve last week, but I have not heard from him.
