add_mask(p_mask: ecpi.common.num.array_square_cell.ArraySquareCell, p_name=None)

elevdir_to_skypix(elev, direction)

convert elevation/direction coordinates into sky pixels coordinates

(0,0) is at the center of the sky array

Parameters:

• elev (float or array(float)) – elevation in degrees
• direction (float or array(float)) – direction in degrees

Returns:

pixels y,z coordinates

Return type:

float, float or array2D(float)

get_elevation_limit_fov_corner()

for special case where mask and detector are square and with the same center return deg

get_elevation_limit_fov_side()

for special case where mask and detector are square and with the same center return deg

get_full_surface_mask()

get_mask_name(p_name)

get_open_surface_mask()

in cm2

get_percent_open_mask()

get_surface_rect_proj()

compute intersection detector and shadow mask then compute its surface

Returns:intersection surface in cm2 Return type:float

get_surface_rect_proj_allmasks()

compute the surface on the detector of the projection of the masks (the coded detector surface). It is source dependent

Returns:coded detector surface in cm2 Return type:float

get_total_photon()

plot_mask()

plot_submasks()

select_mask(p_idx)

set_mask(p_mask)

set_pos_source_fov(elevation, direction)

set definition of the translation vector linked to the source vec_trans_source is also position on mask where photon passed to go on origin

skypix_to_elevdir(pix_y, pix_z)

convert pixel coordinates into elevation and direction

(0,0) is at the center of the sky array.

elevation from 0 to 90. direction from -180 to +180

Parameters:

• pix_y (float) – y coordinate of the source, in pixels.
• pix_z (float) – z coordinates of the source, in pixels.

Returns:

elevation and direction of the source

Return type:

float, float
