We’re having trouble figuring out what range of values can be used as a smoothing parameter, especially when input from a map of smoothing values. What is the acceptable or functional range? How does smoothing affect a value in a cell?
The case that brought this up is one of my students doing a temporal surface interpolated from radiocarbon dates across the western Mediterranean. He’d like to use a value related to the SD of the dates (maybe the CV) to smooth this temporal surface so that smaller SD’s have the surface more closely matching each known date and higher SDs let that surface respond more to the neighboring dates.
