The format of the character columns in the 90prime-mosaic vs. decam *-ccds.fits files differs:

('skyver', '|S19')
('wcsver', '|S1')
('psfver', '|S19')
('skyplver', '|S4')
('wcsplver', '|S4')
('psfplver', '|S4')
('skyver', '|S8')
('wcsver', '|S1')
('psfver', '|S7')
('skyplver', '|S8')
('wcsplver', '|S5')
('psfplver', '|S8')

I don't know whether we care much, in this instance, given that this is just code versioning information. If anybody decides we don't care, feel free to close this issue without addressing.

The skyver, wcsver and psfver are a little funky because we record the git tag plus the most recent commit. So, for example, the 90prime-mosaic file you indicate has, e.g., DR8.0.4-3-g67709eb4 while the decam CCDs file has DR8.0.1 (for some, not all images). So we could fix this column at S19, but that could bite us if we change to tag names that have more strings.

Meanwhile, I'm a little confused by the range of lengths of the [sky,wcs,psf]plver columns, which typically contain things like V2.0 (i.e., the CP PLVER). Specifically, I don't understand why the DECam CCDs file has S8.

I don't think any of these issues are show-stoppers, and since I can't think of an easy fix, I think we should just close this.

Oh, and for the record wcsver is a blank string for both cameras.

wcsver: we used to have separate WCS calib files; now we just do it on the fly.
