.WAVELENGTH [A]: 0.037
[Enter the electron wavelength. For a list of elctron wavelengths
corresponding to different accelerating voltages, see manual
chapter for TF CT or TF CT3.]
.CS [MM]: 2.7
[Enter the spherical aberration constant.]
.MAX. SP. FREQ. [A-1]: 0.10
[Enter the spatial frequency limit in unit of 1/Angstroems. The
maximum spatial frequency is 1/(2*pixel).]
.AMPLITUDE CONTRAST RATIO: 0.09
[Enter the amplitude contrast ratio estimated by TF DDF.]
.SOURCE SIZE [A-1]: 0.003
[Enter an initial guess of the size of the illumination source in
reciprocal Angstroems. This is the size of the source as it appears
in the back focal plane of the objective lens. A small value results
in high coherence; a large value, low coherence.]
.DEFOCUS SPREAD [A]: 200
[Enter estimated magnitude of the defocus variations corresponding
to energy spread and lens current fluctuations.]
.CHARACTER OF THE FILM Kf [A-1]: 0.05
[Enter an initial guess for the parameter of the modulation transfer
function. Actually it includes effects of the scanner, film, etc.]
.GAUSSIAN ENVELOPE CHARACTER [A-1]: 0.05
[Enter initial guess of halfwidth of Gaussian envelope function.]
.IMAGE FILE: rod004
[Enter name of background-corrected 1D profile of power spectrum.]
.DEFOCUS [A]: 20000
[Enter defocus value calculated by 'TF DDF'. Convention: underfocus
is positive, overfocus is negative.]
.FITTING REGION (N1-N2): 30,230
[Enter fitting region in Fourier pixel units.]
.OUTPUT FILE: rop004
[Enter the name of file which will store simulated 1D profile using
the parameters estimated above. Thus, you can compare how well they
fit. If you input a series of files, the output files will be
generated in the same order as the input. If you don't want an
output file, type * to terminate.]
