In SWotherspoon/SGAT: Solar/Satellite Geolocation for Animal Tracking
twilightResiduals R Documentation
Twilight Residuals
Description
Twilight residuals for known locations
Usage
twilightResiduals(twilight, rise, p, zenith = 96)
Arguments
twilight
the observed times of twilight as POSIXct.
rise
logical vector indicating which twilights are sunrise.
p
a two column matrix of (lon,lat) locations
zenith
the solar zenith angle that defines twilight.
Details
Given known locations p, this function calculates the
difference between the predicted and observed twilights for those
locations, where the sign is chosen so that obscuration of the
sensor leads to a positive residual.
Value
a vector twilight residuals (in minutes).
