%%the infile will will be the whole lcd file
%despike function with hard coded trend of .01 and flag of 15
%first difference methode is used for despike processing
%if difference between data value "a" and "b" is greater than .01 than the
%new field in line a will contain the average of 15 pts surrounding "a"
%as same as old processing, running dspike twice will be hard coded as well
%as derived parameters d-a650, d-d-a650 which is in bbop scripts
