ps_ctf_defocus_zeroes()

int ps_ctf_defocus_zeroes	(	Bstring &	filename,
		double	volts,
		double	Cs,
		double	amp_shift
	)

Generates a postscript plot of defocus versus zeroes.

Parameters

&filename	postscript output file name.
volts	accelerating voltage (in volts).
Cs	spherical aberration (in angstrom).
amp_shift	amplitude contribution phase shift (radians).

Returns

int 0.

A postscript plot is generated from microscope and defocus parameters
to show the corresponding defocus and zero values.
Defocus is given in um.

ps_ctf_plot() [1/2]

int ps_ctf_plot	(	Bstring &	filename,
		CTFparam &	em_ctf,
		size_t	n,
		double	freq_step
	)

Generates a postscript plot from CTF parameters for defocus and the envelope.

Parameters

&filename	postscript file name.
&em_ctf	CTF parameter structure.
n	number of reciprocal space steps.
freq_step	spatial frequency increment per step.

Returns

int 0.

Postscript output is generated from microscope and defocus
parameters.

ps_ctf_plot() [2/2]

int ps_ctf_plot	(	long	n,
		double *	rps,
		double	interval,
		CTFparam *	em_ctf,
		Bstring &	filename
	)

Generates a postscript plot of a contrast transfer function.

Parameters

n	number of elements in the radial power spectrum.
*rps	radial power spectrum.
interval	spatial frequency step size.
*em_ctf	CTF parameter structure.
&filename	postscript file name.

Returns

int 0.

Postscript output is generated from fitted defocus, envelope and background
parameters and compared to the radial average of the power spectrum image.

ps_point_spread()

int ps_point_spread	(	Bstring &	filename,
		CTFparam &	em_ctf,
		size_t	n,
		double	freq_step
	)

Generates a point spread plot from CTF envelope parameters.

Parameters

&filename	postscript file name.
&em_ctf	CTF parameter structure.
n	number of reciprocal space steps.
freq_step	spatial frequency increment per step.

Returns

int 0.

Postscript output is generated from microscope and defocus
parameters.

ps_show_ctf_param()

int ps_show_ctf_param	(	Bplot *	plot,
		CTFparam &	em_ctf
	)
