%description
The Swiss Ephemeris (version 2.10.03) is a high precision ephemeris based
upon the DE431 ephemerides from NASA's JPL. It covers the time range 13201
BCE to 17191 CE. This package uses the semi-analytic theory by Steve
Moshier. For faster and more accurate calculations, the compressed Swiss
Ephemeris data is available in the 'swephRdata' package. To access this
data package, run 'install.packages("swephRdata", repos =
"https://rstub.r-universe.dev", type = "source")'. The size of the
'swephRdata' package is approximately 115 MB. The user can also use the
original JPL DE431 data.
