Astronomical Image Processing System 31DEC09 Version

The 31DEC09 version of AIPS is no longer available for installation. It will no longer change even for significant bugs. The MNJ will still work to apply patches, but will only be useful once in 2011 since 31DEC09 will not be changed. The MNJ will fetch changes in the TEXT areas but changed CookBook chapters apply in small part to later releases so this may not be a good idea. You should install the now frozen version 31DEC10 or the current development version 31DEC11.

WHATSNEW in 31DEC09 AIPS

The accounting system has been upgraded to report the total disk I/O in Megabytes at the end of each task. Linux systems do not provide an I/O count in the way that fomer systems, such as VMS, did.

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. 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 2009 will change every Wednesday in 2009 and the numbers in the table are now final.
