ELL_CRV_SPLIT

## Name

ELL_CRV_SPLIT

## Purpose

Split a curve with an azimuth (geodesic or loxodromic).

## Calling Sequence

ell_crv_split, lonc,latc, c, az

## Inputs

lonc, latc = Arrays of lon,lat for a curve. in
c = Refernce point in a structure (lon:lon,lat:lat}. in
az = Azimuth from point c. in

## Keywords

LONL=lonl, LATL=latl Returned points of curve left of azi.
LONR=lonr, LATR=latr Returned points of curve right of azi.
NL=nl, NR=nr Number of points in left and right secctions.
INT=p Intersection point of the curve and azimuth returned
in a structure (lon:lon,lat:lat}.
/LOX Use loxodromic azimuth (else geodesic azimuth).
ERROR=err Error flag: 0=ok.

## Notes

Notes: An azimuth from point c is used to split the given
curve into two parts, that left of the azimuth line, and
that right of the azimuth line as seen from point c.
The interpolated point is included in both sections.
This routine assumes one intersection only.
