DESCRIPTION

WARPFIT determines the RMS deviation for a paraboloid
 with a focal length of 100.8 inches for a maximum of 600 data points.
The rotation angle is set to zero. Data should be free format:
            x(1)    y(1)    z(1)
            x(2)    y(2)    z(2)
             .       .       .  
            x(i)    y(i)    z(i)
 The y-axis runs along the panel centerline
 The x-axis is perpendicular to the centerline
 The z-axis is the depth of the machining measured from the (x,y) plane.
 

PARAMETERS

in
Input ascii file with up to 9 columns of data. No default.
npts
Select the first ``npts'' from the input file. Default reads the whole file or 2000 which is the maximum allowed.
par
Initial estimates for parameters; rotations(degrees) and offsets(inches). Exactly 6 numbers are needed here: xrot,yrot,z0,warp,angle,y0
nfit
Number of paramters to fit. Remaining parameters are fixed. E.g. nfit=3 would only fit xrot,yrot,z0, leaving warp,angle,y0 fixed. Default: nfit=3
swapxy
Swap x and y axes. Y or N, Default=No.
log
Output logfile. It will contain the results, a histogram with residuals and all selected measurements, the fit, and residuals. Default: print results and histogram only to terminal.
