obtain_time_image
(x, y, centroid_x, centroid_y, psi, time_gradient, time_intercept)[source]¶ Create a pulse time image for a toymodel shower. Assumes the time development occurs only along the longitudinal (major) axis of the shower, and scales linearly with distance along the axis.
 Parameters
 xu.Quantity[length]
X camera coordinate to evaluate the time at. Usually the array of pixel X positions
 yu.Quantity[length]
Y camera coordinate to evaluate the time at. Usually the array of pixel Y positions
 centroid_xu.Quantity[length]
X camera coordinate for the centroid of the shower
 centroid_yu.Quantity[length]
Y camera coordinate for the centroid of the shower
 psiconvertible to
astropy.coordinates.Angle
rotation angle about the centroid (0=xaxis)
 time_gradientu.Quantity[time/length]
Rate at which the time changes with distance along the shower axis
 time_interceptu.Quantity[time]
Pulse time at the shower centroid
 Returns
 float or ndarray
Pulse time in nanoseconds at (x, y)
