Section 14: House position calculations

Calculate house position of a given body.

swe_house_pos(armc, geolat, eps, hsys, xpin)

swe_gauquelin_sector(jd_ut, ipl, starname, ephe_flag, imeth, geopos,
  atpress, attemp)

Arguments

armc	right ascension of the MC as double (deg)
geolat	geographic latitude as double (deg)
eps	ecliptic obliquity as double (deg)
hsys	house method, one-letter case sensitive as char
xpin	longitude and latitude of the given body as numeric vector (deg)
jd_ut	UT Julian day number as double (day)
ipl	Body/planet as integer (SE$SUN=0, SE$MOON=1, ... SE$PLUTO=9)
starname	Star name as string ("" for no star)
ephe_flag	Ephemeris flag as integer (SE$FLG_JPLEPH=1, SE$FLG_SWIEPH=2 or SE$FLG_MOSEPH=4)
imeth	Gauquelin method as integer (0, 1, 2, 3, 4 or 5)
geopos	position as numeric vector (longitude, latitude, height)
atpress	Atmospheric pressure as double (hPa)
attemp	Atmospheric temperature as double (Celsius)

Value

swe_house_pos returns a list with named entries: return how far from body's cusp as double, and serr error message as string.

swe_gauquelin_sector returns a list with named entries: return status flag as integer, dgsect for Gauquelin sector as double and serr error message as string
