ell_cer_pac_mod - construct an Ellerbroek-Cerro-Pachon refractive atmospheric model.

Calling Sequence

[ram]=ell_cer_pac_mod(r_0,ref_wvlngth[,tf])

Parameters

• r_0 : r0 in meters.
• ref_wvlngth : r0 reference wavelength in meters.
• tf : the 3D frame.it is the global frame if defaulted
• ram :the output refractive atmospheric model.

Description

construct an Ellerbroek-Cerro-Pachon refractive atmospheric model. this model is proposed by Ellerbroek, JOSA v 19, p 1803. It consists of a six layer atmosphere, with altitudes and relative weights given in the table below:

The power spectrum assumed for these layers is not stated in the paper, Here we assume it satisfy Komolgorov law.

Examples

	r0=0.1;r0_w=1e-6;
	ram=ell_cer_pac_mod(r0,r0_w);
	num=atm_mod_lay_number(ram);
