function airy
Creates an airy function at the center of the array. This is defined by: Telescope diameter [meters], pixel scale [arcsec/pixel], and wavelength [microns]. Optional keywords are naxis1, naxis2 which determine the size of the array. If not set, the size of the array is determined from global variables.
Syntax
result = airy(DIAMETER, PIXELSCALE, WAVELENGTH [, naxis1=value] [, naxis2 = value])
Arguments
| DIAMETER: | The telescope diameter in meters |
| PIXELSCALE: | The size of a pixel in arcseconds |
| WAVELENGTH: | The observing wavelength in microns |
| naxis1=value: | Optional, the size of the resulting array in the first dimension |
| naxis2=value: | Optional, the size of the resulting array in the second dimension |
