Detailed Description

Contains a few support functions for simulation.

Function Documentation

◆ atm2xloc()

void atm2xloc	(	dcell **	opdx,
		const sim_t *	simu
	)

Propagate the atmosphere to closest xloc. skip wavefront sensing and reconstruction.

2011-04-26: opdx was incorrectly computed when atm.ht and atmr.ht does not match in number. Fixed. Do not do scaling even if fit.ht is less.

◆ sim_update_etf()

void sim_update_etf ( sim_t * simu )

Evolving the Sodium layer by updating the elongation transfer function.

◆ sim_update_flags()

void sim_update_flags	(	sim_t *	simu,
		int	isim
	)

Update flags

◆ seeding()

void seeding ( sim_t * simu )

use random number dirived from input seed to seed other stream. necessary to have independant streams for different wfs in threading routines to avoid race condition and have consitent result

◆ init_simu()

sim_t* init_simu	(	const parms_t *	parms,
		powfs_t *	powfs,
		aper_t *	aper,
		recon_t *	recon,
		int	iseed
	)

Initialize simu (of type sim_t) and various simulation data structs. Called for every seed.

◆ free_simu()

void free_simu ( sim_t * simu )

Release memory of simu (of type sim_t) and close files.

◆ print_progress()

void print_progress ( sim_t * simu )

Print out wavefront error information and timing at each time step.

◆ save_skyc()

void save_skyc	(	powfs_t *	powfs,
		recon_t *	recon,
		const parms_t *	parms
	)

Output parameters necessary to run postproc using skyc/skyc.c

◆ blend_screen_side()

void blend_screen_side	(	map_t *	atm1,
		map_t *	atm2,
		long	overx,
		long	overy
	)

overlay atm2 with atm2 according to wind direction angle and required overlapping region of at least overx*overy.

◆ genatm()

void genatm ( sim_t * simu )

wrap of the generic vonkarman_genatm to generate turbulence screens. Wind velocities are set for each screen.

◆ setup_recon_HXW_predict()

void setup_recon_HXW_predict ( sim_t * simu )

Setup ray tracing operator from xloc to ploc, with predictive offsetting
