angular_separation: Angular separation between two celestial bodies

In Susarro/arqastwb: Archaeoastronomy algorithms

Description

Angular separation between two celestial bodies

Usage

angular_separation(declination1, right_ascension1, declination2,
  right_ascension2)

Arguments

declination1	Declination of first celestial body in degrees
right_ascension1	Right ascension of first celestial body in hour angle
declination2	Declination of second celestial body in degrees
right_ascension2	Right ascension of second celestial body in hour angle

Value

Angular separation

Examples

declination1<-str2degrees("19<c3><82><c2><ba>10'57\u0022")
right_ascension1<-str2hours("14:15:39.7")
declination2<-str2degrees("-11<c3><82><c2><ba>09'41\u0022")
right_ascension2<-str2hours("13:25:11.6")
angular_separation(declination1,right_ascension1, declination2, right_ascension2)
