)error multiplication factor(s) for GPS locations, can be a scalar (x = y) or vector of length 2 (x != y)
error multiplication factors for Argos longitude classes 3, 2, 1, 0, A, B (Z assumed equal to B)
error multiplication factors for Argos latitude classes 3, 2, 1, 0, A, B (Z assumed equal to B)
Error Multiplication Factors for Argos (and GPS) locations. Default assumption is that GPS locations are 10x more accurate than Argos lc 3 in both x and y directions.
User-specified Error Multiplication Factors (emf). emf's must be provided as a data.frame with the following columns:
emf.x emf values for the x direction
emf.y emf values for y direction
lc location class designations
The location class designations can be the standard Argos lc values: 3, 2, 1, 0, A, B, Z or other values. The number of classes specified is flexible though may not be amenable to a large number of classes. Whatever class designations are chosen must also appear in the input data lc column. A GPS location class ("G") is provided by default and assumes that GPS locations are 10 x more precise than Argos lc 3 locations.
