With this utility you can wrap your interferogram to arbitrary interval instead of [-pi, pi). Can be used for example to make fringes correspond to, e.g., 1 cm displacement.
PROGRAM: wrap wraps float binary file to interval [a,b) USAGE: wrap infile [a b [ofile]] EXAMPLE: wrap interferogram.raw -4pi 4pi interf4.raw default \outputfile == infile.wrap default interval [a b) == [-pi pi)
