MIRIAD Introduction

What is MIRIAD?

MIRIAD (Multichannel Image Reconstruction, Image Analysis and Display) is a toolbox, in the form of an environment with a large set of moderate-sized program which perform individual tasks, involving calibration, mapping, deconvolution and image analysis of interferometric data. MIRIAD software is also part of the Hat Creek telescope control software; data obtained from the telescopes is directly written into MIRIAD format with a MIRIAD user interface.

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 (not sure how much longer supported)). Most of the code is written in Fortran 77, with some lower level I/O routine in ANSI-C. The core (C) library of MIRIAD is also used in AIPS++.



To install MIRIAD, please consult the install.MIR document. It describes how you can obtain out our daily daily CVS snapshot file from our anonymous ftp that forms the base for installing MIRIAD, and walks you through an installation. Installations are supported for Linux, SUN workstations (both SunOS 4.x and 5.x are supported), ConvexOS, HP/UX, SGI/IRIX, and IBM/AIX, but check the system files, as new systems have been added recently.

Local Deviations (old)

Each MIRIAD site may have local deviations that are not described in the general documents. The directory $MIR/local is set aside for implementing these. Your $MIR/MIRRC.local startup script, that is automatically used by your MIRIAD setup, contains all the pointers to these local deviations.

The following sites have supported versions of MIRIAD (several unofficial versions float around the globe) with the following (known) deviations from the standard export version (see the listed local MIRIAD manager for problems):
