AIPS release information
========================

We introduced a fairer system of counting shipped AIPS versions, in
which a 'source only' shipment combined with a 'binaries' shipment is
now counted as only one shipment. This reduces the previously
published numbers: the total number of shipped versions of 15JUL95
AIPS is now 189, and the current number for 15JAN96 AIPS is 140 (the
latter number is still rising). These numbers are still higher than
that of any previous AIPS release. The percentage of shipments using
anonymous ftp appears to have stabilized at 80%, and the percentage of
shipments which include binaries at roughly 60%.

Personnel
=========

In March 1996, Ketan Desai joined the AIPS group to work on software
to support the OVLBI project. In April 1996, Eric Greisen decided to
leave the AIPS group, which is a great loss to the AIPS project. The
AIPS group currently consists of approximately 6 FTE's, who have to
share the load of developing new software (primarily VLBA and OVLBI),
maintaining existing software, supporting the world-wide community of
users, and maintaining the AIPS installations at both sites.

General Developments
====================

New bandpass calibration modes were added, specifically bandpass
interpolation, with correct treatment of flagged BP entries, and
allowing weighted and unweighted two-point interpolation. Other new
developments in the general area concentrated on increasing the
overall robustness, and implementing changes and improvements as
suggested by the AIPS user community.
