First, thanks for the input. I was not sure how relevant it was to lunars (which seem much more complicated).
Yes, (12) should use 60*180/pi... That is why these write-ups should be sent to reviewers.
As for radians being dimensionless, that seems to be the terminology people use (per a google search). The main point was to explicitly write down how these approximations show up, and how/when radians must be used. Mostly for my own notes.
