______________________________________________________________________________ RT REVTRANS computes the inverse fourier transform of a file which contains the fourier transform of another file. The input file is assumed to have been written by PWRSPEC, or to be in the format used by PWRSPEC. The input format can be REAL*4 or COMPLEX*8. For REAL*4 files, the real and imaginary parts are assumed to be located in every other pixel location. Files with REAL*4 data can contain subframes such as the UM speckle format. The real part of the inverse transform is always written to a REAL*4 file and optionally, the imaginary part can be written to a REAL*4 file. ______________________________________________________________________________ Enter an option: 1-APR-1995 23:04:20.14 OPTION=RT REVTRANS, Version 2 Open the file whose inverse transform is to be computed Enter the filename: (<CR> for default) FILE_IN=PTCE There is one map in the file Reading from the file 100 rows of 102 pixels in R4 format Enter the number of dimensions the transform was based on: (default = 2) DIMENSION= 2 Was the number of columns in the original file even? (default = Y) EVEN= T Enter the name of the file to contain the real part of the inverse transform: (default = RPTCE) FILE_OUT_REAL= RPTCE Creating new file For the real output file Enter the ouput map number(s): (default = 1) MAPS_OUT= 1 Enter the name of the file to contain the imaginary part; enter "-" for no imaginary file: (default = IPTCE) FILE_OUT_IMAGINARY= IPTCE Creating new file For the imaginary output file Enter the ouput map number(s): (default = 1) MAPS_OUT= 1 ______________________________________________________________________________
