CFwhm:X
The X method returns the centroid x position obtained when the FWHM is computed by the Calc method.
|
nX = CFwhm:X() |
nX is the centroid pixel
coordinate for the x axis.
|
F = CFwhm:new() |
-- create a new CFwhm object |
|
F:Calc( 290, 484 ) |
-- calculate the FWHM near pixel 290,484 |
|
Printf("X=%.3lf", F:X() ) |
-- result: X = 483.442 |
