[fitsbits] Comments on proposed FITS draft v3.0

[Peter Weilbacher]

Hi FITS gurus,

I have looked through the changes of the FITS standard as proposed in 
the v3.0 draft and have a two minor comments.

In Sect. 4.4.2.3, the ADS ID is recommended to be used in the REFERENC 
keyword. Recently I more and more noticed the use of DOI numbers for 
stuff like this (see http://doi.org/). As this seems to be standardized 
across many more disciplines than just Physics and Astronomy, should 
this not be the recommended way to store a reference? Or perhaps 
recommend this in addition to the ADS reference?

Other than that I just noticed that in Table 8.6 footnote 1 is never 
quoted. I guess it should be quoted from the caption as in Table 8.5...

Great to see that the units to be used in FITS headers are now 
explicitely mentioned in the standard, and that they are marked as case 
sensitive, too.

Best regards,
    Peter.
