IDL hates python? 1 54 (6/23/2011 12:05:52 PM) comp.lang.idl-pvwave Hi all, As part of my very long and complicated IDL program (running in IDL 8.0.1), I use SPAWN to call a package (that I didn't write) which involves some Python routines; example code, very stripped down: f... Gray

HASH -- bug, or "feature"? 2 47 (4/20/2011 7:12:52 PM) comp.lang.idl-pvwave Can anyone tell me why, when you create a hash, the elements are not in the order of the keys you give? And, even worse, when you index a hash with an array of keys, the resulting hash does not come out in the... Gray

Improve contrast with ASINHSCL 4 41 (4/11/2011 3:42:37 PM) comp.lang.idl-pvwave Hi all, Can anyone tell me how to improve contrast when I'm asinh scaling and image? The tip on idlcoyote.com doesn't really go into it. I'm assuming it has to do with the beta parameter, but I'm not sure ho... Gray

Interpolate between two curves 1 646 (3/25/2011 11:40:28 PM) comp.lang.idl-pvwave Hi all, I have a large set (>10,000) of x,y data points, and two non- overlapping curves (2nd-degree poly fits): y = a1*x^2+b1*x+c1 y = a2*x^2+b2*x+c2 Curve 1 has z=0 and curve 2 has z=5; z values change... Gray

zenpos vs. SkyCalendar 1 28 (3/15/2011 11:04:03 PM) comp.lang.idl-pvwave Hi all, I'm trying to use ZENPOS from the IDL Astronomy Library, but I'm not getting the results I expect. If I compare with SkyCalendar (http:// preview.tinyurl.com/495ys8l) for Kitt Peak, I get: Date (eve/... Gray
