source_dx_dy

lstchain.reco.utils.source_dx_dy(source_pos_x, source_pos_y, cog_x, cog_y)

Compute the coordinates of the vector (dx, dy) from the center of gravity to the source position

Parameters:

source_pos_x: X coordinate of the source in the camera

source_pos_y: Y coordinate of the source in the camera

cog_x: X coordinate of the center of gravity in the camera

cog_y: Y coordinate of the center of gravity in the camera

Returns:

(dx, dy)
