power_law - construct a power law for turbulent spectrum.

Calling Sequence

[pl]=power_law(r_0_meters,r_0_ref_wavelength_meters[,exponent])

Parameters

• r_0_meters : r0 in meters.
• r_0_ref_wavelength_meters : the r0 reference wavelength in meters.
• exponent : pow exponent. -11/3.0 is defaulted (Kolmogrov pow law).
• pl : the output power law

Description

construct a power law for turbulent spectrum.

Examples

	pl=power_law(0.1,1e-6);
	in=null_inner();
	ps=power_spectrum(pl,in);
