MIRIAD V4 is the official release. The current development version is 4.0.5 (as of Aug 21, 2004), available via CVS. The MIRIAD V3 release is still available under a CVS branchname MIR3 but is not further developed, except serious bug fixes (the last official version is 3.1.1). We still recommend MIRIAD V3 for (BIMA) production work, and MIRIAD V4 if you need to work with non-BIMA data, large files and/or large number of antennae (e.g. ATA, ALMA or LOFAR) for simulations. For general image analysis MIRIAD V4 should also be used. The ATNF version of MIRIAD is (as of Aug 21, 2006) currently being merged into MIRIAD V5 (branchname: MIR5).
MIRIAD (Multichannel Image Reconstruction, Image Analysis and Display) is a toolbox, in the form of an environment with a large set of moderate-sized programs which perform individual tasks, involving calibration, mapping, deconvolution and image analysis of interferometric data. MIRIAD software was also used in parts of the Hat Creek (BIMA) telescope control software; data obtained from the telescopes is directly written into MIRIAD format with a MIRIAD user interface.

A little history: MIRIAD was originally developed in 1987 on Sun workstations (SUN OS 3.2), but has since then been ported to a large number of UNIX flavors (SUN OS 4.x, 5.x, SGI/IRIX, HP/UX, ConvexOS, DEC Alpha, LINUX, and VAX/VMS. Most of the code is written in Fortran 77, with some lower level I/O routine in ANSI-C, also available as a seperate library "mirlib". This core (C) library of MIRIAD is also used in AIPS++ and the CARMA online system.

Two slightly different distributions of MIRIAD currently exist: the original BIMA release (now called CARMA or V4), and the ATNF release. This page is the homepage for the CARMA release of MIRIAD, but we are working on making the difference between MIRIAD-A and MIRIAD-B as small as possible, and you will find most, if not all, ATNF routines in the CARMA release of MIRIAD.

On 5-mar-2001 the Illinois RCS archive of 15-feb-2001 was converted for CVS at Maryland. You can now find daily CVS snapshot (source code only, but including CVS tags) and stable releases with binaries for some popular architectures in the anonymous ftp area.
