Astronomical Image Processing System 31DEC07 Version

The 31DEC07 version of AIPS has been frozen for about one year except for a number of patches made in 2008. It is no longer available for installation. The MNJ will no longer work to allow the application of patches. You should install the frozen version 31DEC09 or the current development version 31DEC10.

WHATSNEW in 31DEC07 AIPS

All "array processor" code has been changed to use dynamic memory rather than a fixed pre-compiled memory allocation. Large problems will request large amounts of memory but many will run in smaller memory if they have to. Small problems will not demand the large memories previously required to support the largest problems.

Distribution Statistics

Tools to monitor shipments of the tar balls and the binary releases as well as accesses of the cvs code maintenance system have been created and run since Spring 2003. We estimate "sites" by counting unique IP addresses. In each of the totals, an individual IP address is counted only once. In general, an IP address is used by only one user, but more than one IP address will be used by those users that use dial-up connections. Thus, these totals are a modest over-estimate. However, they are an underestimate of the number of computers used for AIPS since at many institutions a single IP address is used to provide AIPS to a number of computers. The table below shows the totals in various categories and has links to the plots of the cumulative totals. Note that the TST and NEW numbers for 2003 are for only part of the year as, of course, are all the 2007 numbers. These are indicated by the asterisk. The totals for TST and NEW include both binary and tar-ball downloads. The binary totals include binary downloads and binary MNJ accesses.

The plot for 2007 has stopped changing and the numbers are complete.
