[fitsbits] ADASS FITS BoF on Sunday
ADASS 2004 FITS BoF on Sunday Afternoon
--------------------------------------- The FITS Birds-of-a-Feather (BoF) session at this year's ADASS meeting in Pasadena will be held earlier than usual, on Sunday October 24th from 4:30 to 6:00 pm (i.e., shortly before the opening reception). I hope many of will be able to attend. This BoF session will present a summary of current activities in the FITS user community and will provide a forum for the discussion of current issues. The tentative agenda is: * Recent changes to the IAU and Regional FITS committees and their membership * Overview of new streamlined approval procedures for FITS proposals * Status of current FITS proposals - FITS MIME types - World Coordinate Systems Papers III and IV - TDIMn and Variable Length array conventions for binary tables * Ideas for establishing a registry for FITS conventions * The role of FITS in the VO era: are any changes desired? * Open forum for short presentations on FITS topics by attendees - Simple Imaging Polynomial (SIP) representation of distortions - any other topics Please let me know if you have ideas for other topics (regardless of whether you plan to attend the meeting).

I shall not be at ADASS, unfortunately, but one topic raised on this list recently is of interest to me: whether we can overcome the limits implied by 32-bit integers. With the help of Bill and his colleagues at GSFC I was able to build a version of cFITSIO which handled files of over 2 GB, but I think a 2 gigarow limit in tables may be enforced by the presence of implicitly 32-bit signed integers for NAXIS2 (etc.) in the headers. It would be interesting to know whether any other people have an interest in extending FITS beyond the 32-bit limit, and whether they have ideas to help solve it.
