 |== Welcome to the Extract_Rec_Region program ==|
 It allows you to extract a rectangular sub-domain
 of recon data produced by PPR as long as it does
 not cross the dateline (to be fixed!). Extracted
 data are then averaged and smoothed for analysis
 and the standard deviations and standard errors
 of the mean for each year are calculated. Running
 this program requires the XY coordinate file used
 by PPR and the recon data file produced by PPR.
