Function Documentation

◆ mapnew()

map_t* mapnew	(	long	nx,
		long	ny,
		real	dx,
		real	dy
	)

create a new map_t object.

◆ mapnew2()

map_t* mapnew2 ( map_t * A )

ceate a new map_t object from existing one. P is left empty.

◆ mapcircle()

void mapcircle	(	map_t *	map,
		real	r,
		real	val
	)

Create a circular aperture on map_t.

◆ map_d_din()

void map_d_din	(	map_t *	map,
		real *	d,
		real *	din
	)

Find the inner and outer diameter of an amplitude map contained in map_t.

◆ create_metapupil()

void create_metapupil	(	map_t **	mapout,
		long *	nxout,
		long *	nyout,
		dmat *	dirs,
		real	D,
		real	ht0,
		real	dx,
		real	dy,
		real	offset,
		real	guard,
		long	ninx,
		long	niny,
		int	pad,
		int	square
	)

create a metapupil map, with size nx*ny, origin at (ox,oy), sampling of dx, dy, height of ht, that can cover all the directions specified in dirs

offset: distance in pixel from the point closest to the origin to origin (right side). 0: there is a point on the origin. 1/2: the closest point to origin is 1/2 pixel.

pad!=0: round nx, ny to power of 2.

Parameters

[out]	mapout	map
[out]	nxout	nx
[out]	nyout	ny
[in]	dirs	All Directions to cover (thetax, thetay, hs, hc)
[in]	D	Diameter (meter)
[in]	ht0	Conjugation Height (meter)
[in]	dx	Sampling along x (meter)
[in]	dy	Sampling along y (meter)
[in]	offset	Fractional offset of point closet from origin. between [0, 1)
[in]	guard	Width of guard area, in meter
[in]	ninx	Suggested size along x
[in]	niny	Suggested size along y
[in]	pad	Increase nx, ny to power of 2
[in]	square	Full square/rectangular grid

◆ d2map()

map_t* d2map ( const dmat * in )

convert a dmat to map_t.

keywords are used to specify parameters:

the sampling (dx or D; strong recommended; default to 1/64; also specify dy if spacing is different.),
layer heiht (default to 0),
frozen flow speed (vx, vy)
origin (ox, oy; will use nx/2*dx or ny/2*dy if not specified)
for DM grid only: inter-actuator-coupling (iac)

◆ dcell2map()

mapcell* dcell2map ( const dcell * in )

convert a mmap'ed dcell to map_t array

◆ d2rmap()

rmap_t* d2rmap ( const dmat * in )

convert a dmat to rmap_t.

keywords are used to specify parameters:

the sampling (dx or D; strong recommended; default to 1/64; also specify dy if spacing is different.),
origin (ox, oy; will use nx/2*dx or ny/2*dy if not specified)
txdeg, dydeg: tilt of surface in degree wrt beam. only 1 can be less than 90 degree.
ftel: focal length of the telescope
fexit: distance from exit pupil to focus
fsurf distance from surface to focu

◆ dcell2rmap()

rmap_t** dcell2rmap	(	int *	nlayer,
		const dcell *	in
	)

convert a mmap'ed dcell to map_t array

◆ map_header()

void map_header ( map_t * map )

convert fields to keyword string

◆ rmap_header()

void rmap_header ( rmap_t * map )
