Methods Documentation

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()

in cm2

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_total_photon()

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 -pi to +pi

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
