function sersic2d
Creates a 2D sersic. The sersic function is defined as y(x) = exp(-bn * (x/Re)^(1/n) - 1), with bn = 1.9992 * n - 0.3271.
Syntax
result = sersic2d(c, x0, y0, angle, q, n [, naxis1=value] [, naxis2 = value])
Arguments
| Re: | Effective radius that encloses half of the total light |
| x0: | x-position of center |
| y0: | y-position of center |
| angle: | angle in degrees |
| q: | diskiness |
| n: | shape of light model (0.5 = gaussian, 1 = exponential, 4 = de Vaucouleurs) |
Examples
result = sersic2d(10,80,70,870,-2,1, naxis1=128, naxis2=128)
