The "AIPS++ Reuse Analysis Test" has been designed to address the
ability of AIPS++ to be adapted to the needs of the ALMA
reduction software. It has been divided into three parts:

Phase I Implementation of PdBI (Plateau de Bure Interferometer)
calibration engines inside AIPS++;

Phase II Test of the calibration extensions implemented in Phase I and
of the native AIPS++ capabilities (in particular,
imaging capabilities) on a fair sample of PdBI data sets by a panel of
testers outside the AIPS++ team;

Phase III Benchmarking of AIPS++ on ALMA-size data sets using the
calibration extensions implemented in Phase I.

This report addresses every aspect linked to Phase II. Section 2 details
the findings on the test charge as seen from Phase II.
Section 3 is a collection of recommendations to the AIPS++ project.
These findings and recommendations follow naturally from
the experience gained during Phase II, which is summarized in Appendix
A. In all sections of this appendix, the text gives only
the mean of a response sample whose dispersion is sometimes large. We
thus encourage the reader to go through all the
questionnaires available in Appendices B through H, to obtain an idea of
the full range of feedback.
