[fitsbits] Start of the 'INHERIT' Public Comment Period

Some might suggest that with the abundance of low cost disk space that is now available, the inherit convention is trying to fix a non-problem. The diskspace may be a non-problem (although this is a quirky opinion coming from a FITS compression stalwart :–) I see it mainly as a cost/benefit issue. Compression can reduce the size of an image by a large factor and hence is probably worth the cost of added software complexity. The INHERIT convention on the other hand only reduces the size of the FITS file by a small fraction of 1% in typical cases. (e.g., each additional keyword in the header of a 2000 x 2000 x 16-bit CCD image only increases the file size by 0.001%. but the underlying question is about the purpose of registering conventions in the first place. Nobody has suggested that the inherit convention shouldn't be documented in the registry. The main issue that Bob raised earlier is whether the IAUFWG (or anyone else for that matter) should be able to ofter any advice, or recommendations, to potential new users of the convention, beyond simply documenting what keywords are used by the convention. This is a general issue that will affect a number of conventions, not just the inherit convention. If the IAUFWG decides this would be useful, then a mechanism for adding usage comments or recommendations could be added to the Registry. Bill Pence |
