The DRAO export software package

Over the years, the computing staff at the Dominion Radio Astrophysical Observatory (DRAO) have developed an extensive package of software for the analysis of radio-astronomical data. Recently, the Observatory, in conjunction with a number of Canadian and foreign institutions, has embarked upon an extensive survey of radio emission from the Galactic Plane. This has required the conversion of the DRAG software environment for visibility and image processing into an exportable form that is relatively easily installed at foreign sites. This package is now freely available to the general astronomical community by anonymous ftp. Although the visibility-analysis portions of the package are of little use outside of DRAG, other portions are of general interest. The general philosophy behind the software and its scope are outlined.
