Strange angular measure notation?

Hello all,

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.

Can anyone confirm what this notation is supposed mean?

Thanks!

I think it means a decimal fraction of a minute of arc or a second of
arc.
