nmnLX | R Documentation |
This function calculates the declination of the northern minor Lunar Extreme for a given year, based upon obliquity estimation and corrected average parallax.
nmnLX(
year = skyscapeR.env$cur.year,
loc = FALSE,
parallax = 0.952,
altitude = 0,
verbose = TRUE
)
year |
Year for which to calculate the declination. Defaults to present year as given by Sys.Date. |
loc |
(Optional) This can be either the latitude of the location, or a skyscapeR.horizon object. If missing or FALSE, function will output geocentric declination. |
parallax |
(Optional) Average parallax value for the moon Defaults to 0.952. |
altitude |
(Optional) Altitude of the sun. Defaults to 0 degrees. |
verbose |
(Optional) Boolean to control output of warnings and messages. Defaults to TRUE. |
