[fitsbits] reopening of Public Comment Period on the compression conventions

[Lucio Chiappetti]

ANNOUNCEMENT:  START OF FORMAL PUBLIC COMMENT PERIOD

This is to announce the official reopening of a formal Public Comment 
Period on the incorporation of the Tiled Image Compression and Tiled Table 
Compression conventions in the FITS Standard.

A previous PCP was held in June-July (started on 16 Jun 2015).

We are now re-opening the Public Comment Period to collect comments on the 
modified text, ONE CONVENTION AT A TIME. When the PCP is over, IAUFWG will 
vote on one convention in turn, while the next one will be offered for 
public comments, and so on.

The second convention if the list, to be discussed NOW defines the
Tiled Image Compression and Tiled Table Compression conventions.

The proposed text consists

- in the ADDITION of an entire new chapter (10)  to the FITS Standard
   Document which describes the two conventions in a common prescriptive
   framework.
- It also includes the ADDITION of a new non-prescriptive Appendix I,

Only minor re-wording were applied w.r.t. the earlier version. Considering 
that, despite its complexity, the proposal did not receive any substantial 
objections, I am reopening the PCP for TWO WEEKS (in order to speed up the 
cumulative prcoess dealing with all conventions), but this can be extended 
if requested and motivated.

The updated draft text is available at
http://sax.iasf-milano.inaf.it/~lucio/FITS/Conventions/compression-rev.pdf

- the relevant bibliographic references, and appendices C and H.3 will be
   updated accordingly at the end of the convention incorporation procedure
   (this text is NOT shown but a cumulative draft is available at
   http://sax.iasf-milano.inaf.it/~lucio/FITS/Conventions/commonapps-rev.pdf

Please review the text carefully and post any comments, criticisms, or
suggestions on the FITSBITS mailing list.
