compute_theta2

lstchain.reco.utils.compute_theta2(data, source_position, conversion_factor=2.0)

Computes a square of theta (angle from z-axis) from camera frame coordinates

Parameters:

pandas.DataFrame data: Input data

2D array (x,y) source_position: Observed source position in astropy.units.m

float conversion_factor: Conversion factor (default 0.1/0.05 deg/m)

Returns:

Array with theta2 values
