One obstacle to delivering documentation has been the previously stated intention of doing it in a TeX-compatible format. This has introduced a significant amount of drag, and it was suggested that it be dropped. It was also stated that the classic approach of documenting before coding was inapplicable because latter-day revelations about the instrumental behavior have necessitated prototyping well into the stage where algorithm design was supposed to be over and implementation was to be the major activity.
The relaxation of the documentation format is one attempt to speed up the process of preparing subsystems for design reviews. It should also be noted that the entire reason for scheduling TAPELOAD and PIXCAL/PIXPHOT deliveries on July 1 was so that the developers could proceed to work on their other subsystems, not because any system integration is scheduled to take place in the near term.
The discussion then turned to the question of whether the current pipeline processing was still continuing to divert developers' attention from 2MAPPS design and implementation. It appeared that such distraction was indeed subsiding rapidly, and it was agreed that we should make every effort to disengage immediately, let the DMT run the pipeline, and let the analysis specialists take over worrying about the April '95 data.
It turned out that G. Laughlin had already been working on such a procedure and has distributed an email memo inviting developers to contribute information usefule for the automated checking, if they so desire. The processing status is updated regularly and is available for perusal on the World-Wide Web via http://www.ipac.caltech.edu/2mass/2mass.html (select the Protocamera Processing Status option); access is restricted to 2MASS personnel via the user-ID/password documented elsewhere.
Some photometric dispersion is seen that is not yet understood. There appears to be a variable offset between KAMPHOT and DAOPHOT magnitudes, and this increases the dispersion in the hybrid photometry. It is hoped that an improved PSF grid will permit the DAOPHOT part to be jettisoned. Meanwhile, the nature of the variable offset will be studied.
