tmt_srd_v13_cn2_mod - construct a TMT-SRD-v13-Cn2 refractive atmospheric model.

Calling Sequence

[ram]=tmt_srd_v13_cn2_mod([tf])

Parameters

• tf : the 3D frame.it is the global frame if defaulted
• ram :the output refractive atmospheric model.

Description

construct TMT SRD v13 Cn2 refractive atmospheric model. It implement the refractive atmospheric model proposed by the Science Advisory Committe for the Thirty Meter Telescope project in version 13 of the TMT Science Requirements Document. This model consists of a seven 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

	ram=tmt_srd_v13_cn2_mod();
	num=atm_mod_lay_number(ram);
