Fiducial Module

check_within_fiducial(CoreX, CoreY)

Checks if reconstructed core position is within fiducial area.

Parameters:
  • CoreX –

    X coord. of rec. shower core.

  • CoreY –

    Y coord of rec. shower core.
Returns:
  • out( array or bool ) –

    return TRUE if rec. core inside fiducial area.
