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
