Re: file naming

[<aah@nofs.navy.mil>]

As I mentioned earlier, the other method of keeping 8x3
but making files more unique is to do away with the
.fit/.fts extension and use those extra 3 characters.
Then you could have files more like what I personally
use (and like), such as
    sjjjjft.xxx
    s = site
    jjjj = last 4 digits of the Julian Date
    f = filter name (bvri)
    t = image type (r=raw, p=processed, b=bias,
         d=dark, f=flat)
    xxx = sequence number, starting at 000
Note this format even has a spare digit for future
expansion.  However, it does not uniquely identify
the file as fits, and I bet some processing programs
would barf at numeric extensions.  (it works fine
with iraf, however, which is why I can get away with it.)
  So the question to the list is:  are there any
strong objections to either proposed method:
  (1) .fit/.fts extension with site-named directories
  (2) sequence number extension, no directories needed
Note that, again, this file-naming format is primarily for
CD standarization.  One could copy the files from CD and add
a .fits extension for hard disk use.
