Objet: [Kstars-devel]  Refraction question from KStars

A question she came with and I haven't manage to explain is why do we
have in our code the formula from Meeus multiplied with the factor
1/60 [1]?
I have to mention that she initially implemented the one from Meeus
and got some big values of the refraction correction (order of 1-2
degrees), so I guess there must be some reason behind it, which I
can't identify.

A wild guess would be that the formula gives the refraction in degree (resp. arcmin) and that kstars expects arcmin (resp. arcsec)?
