I have run into a few older papers that have some angular measure
notation with which I'm unfamiliar.

For example, 0.'25 and 0."25, with the quote marks directly over the
decimal point in each case.

I suspect that these denote 25 arcmin and 25 arcsec respectively, but
I'd like to be sure about that.

I'm sure your interpretation is correct. It is a common style to attach
units to the integer part of a value. You see it in new papers as well,
although the trend is definitely away from it. In astronomy, it also
shows up in other notation, such as RA = 5h.3 (with the 'h'
superscripted).

Thanks, Chris. Yes, I did see that sort of notation for RA. I ran
into the tickmarks-on-the-integer oddity in a Soviet paper from 1964;
I wasn't positive that it wasn't some form of grad measure notation.
Thanks for clearing that up.
