Dear Allard,

I need your codes for curve fitting.
Currently I can not download it.
I also need your suggestion about my work.
I want to extract pheno-pauses from NDVI time-series.
I after fitting curve, I need to extract time of phenology according to a fixed NDVI values that is different for every pixel.
Need your suggestions guys.
New to IDL also,

Regards
Sawaid
