emcSetAstigmator

NAME

emcSetAstigmator - Change the astigmator settings

SYNOPSIS

#include "emc.h"
int emcSetAstigmator(EM *em, int units, int correction, int relative,
                     double x, double y);

DESCRIPTION

emcSetAstigmator() sets the current astigmator values of the instrument.

*em

points to an EM control and communications structure that was returned by the emcOpen() call.

units

the units the values are expressed in:

UNCALIBRATED_UNITS	Native astigmator units of instrument
ANGSTROM_UNITS	Units are measured in angstroms
NANOMETER_UNITS	Units are measured in nanometers
MICRON_UNITS	Units are measured in microns
PIXEL_UNITS	Units are measured in pixels in current camera

correction

Boolean value which enables correction of known side effects of this function.

relative

Flags what the astigmator change is relative to:

EMC_RELATIVE	Astigmator change measured relative to current value
EMC_ABSOLUTE	Astigmator change measured relative to "no astigmator change" (absolute setting)

x

the amount of X-axis astigmator change

y

the amount of Y-axis astigmator change
