Astronomical Image Processing System 31DEC12 Version

The 31DEC12 version of AIPS is no longer available for installation. In 2013, it was changed only for fixes of egregious errors ("patches"). In 2014, you may still run MNJs on 31DEC12 if you insist. You need only run one after October 25, 2013 to have all updates to the code. Text files such as CookBook chapters, AIPSLetters, and VLA antenna position corrections are added to version-independent areas and new ones will therfore be copied whenever a MNJ is run. In 2014, 31DEC12 will NOT be patched even to correct egregious problems.

You WILL want a Midnight Job!

If your site has a need for the current version of AIPS with updates via the Internet and the so-called midnight job, Read this information. It has additional information and instructions. Or Eric Greisen for further information.

Since releases of AIPS are planned to be only on an annual basis, the midnight job (now with easier setup and NO ssh) will be the only way for AIPS users outside of NRAO to avail themselves in a timely fashion of whatever enhancements, changes, or new functionality we add to Classic AIPS. In 31DEC12, this will constitute only major bug fixes ("patches") and new documentation files.

The MNJ is the only way in which you can fetch changes to your version of AIPS, other than a full re-installation. It works for both binary and text installations and is sometimes useful even for the "frozen" version of AIPS, since the most recent frozen version will be patched to correct egregious errors.

WHATSNEW in 31DEC12 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 former 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. 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 and numbers for 2012 are now final.
