When I "MSCCMATCH" the individual frames I am left with significant residuals (up to 1 pixel in a wave-like pattern) in the y direction (delta_y vs. y, or the "s" key). ...   1654 2 By: tiraf 05/28/2009 02:38PM Creating a new TaskStarted by:Lianne, 11/26/2008 05:05PM I'm trying to create a new task in Iraf.

I've searched online but haven't found anything to this effect. Any ideas? Thanks!

With IRAF 2.15 and 2.16 and the "macosx" binaries, I'm getting incorrect values when reading double-precision images, corrupting subsequent processing. I can reproduce the problem simply by doing this: [code:1:652f259940]imarith de...   3873 9 By: jturner 09/04/2012 08:10PM Copying WCS Distortions to a new ImageStarted by:joshw, 04/23/2010 09:52PM Hi, I'm trying to set up a process by which I can add accurate WCS to images in an automated way. The images have little or no WCS info embedded in the header to begin with and my first step is to solve using the Astrometry.net software. This inserts...   1928 0 By: joshw 04/23/2010 09:52PM Coordinate file generated by daofind ...Started by:Arghya, 05/24/2022 01:38PM Hi , I am currently a beginner with IRAF and am trying to overplot the coordinate file generated by Daofind package , but unfortunately the file has no data , only the header names ,format and units.

Basically I am calculating rotational velocities for the stars using the technique as stated in Bailer-Jones et al. 2004, A&A, 419, 703. I would like to know if IRAF can do ...   1371 1 By: fitz 04/27/2010 10:58PM Converting from cd matrix to crota/cd...Started by:hberrier, 09/23/2008 08:37PM Hi, I'm trying to use a galaxy photometry routine created by my advisor that requires the wcs header keywords "crota" and "cdelt".

Is there a quick way to convert from the cd matrix t...   4032 2 By: hberrier 09/23/2008 08:37PM converting fits to psStarted by:Guest, 03/14/2006 12:28PM Dear IRAF team, I would like to convert a 1D spectrum from fits or imh to a postscript or encapsuled image. When I use the "export" command, it saves the 2D image of the specrum (i.e. a line of pixels in a frame). Could you tell me please whether there ...   6455 3 By: fitz 03/14/2006 12:28PM Convert MM/DD/YYYY to MJDStarted by:aaron, 08/16/2008 09:19PM Hello, I have a simple question. Is there a routine inside of IRAF to convert standard calendar time into MJD? I don't need it to be specific to the hour or second, just the day. If so, which package is it under? I can't seem to find the routine called...   3171 2 By: aaron 08/16/2008 09:19PM Convert 2D spectra to ascii fileStarted by:Cindy Wu, 02/25/2009 08:18PM I have a question regarding IRAF commands.

And an extension to this question is, can I easily create a .jpg that shows both the .fit image I want and also overlain on that, say a BPM.
