Phi angle in CM frame for different runs

$\varphi^{LAB}$

The angle is (-30, 330).

	electron sector=1	electron sector=6
$\varphi_{e}^{LAB}$
$\varphi_{pion}^{LAB}$
$\varphi_{e}^{LAB} - \varphi_{pion}^{LAB}$

The angle is (0, 360).

	electron sector=1	electron sector=6
$\varphi_{e}^{LAB}$
$\varphi_{pion}^{LAB}$
$\varphi_{e}^{LAB} - \varphi_{pion}^{LAB}$

$\varphi^{CM}$

The angle is (0, 360).

	electron sector=1	electron sector=6
$\varphi_{e}^{CM}$
$\varphi_{pion}^{CM}$
$\varphi_{e}^{CM} - \varphi_{pion}^{CM}$

electron sector	$\varphi_{e}^{CM}$	$\varphi_{pion}^{CM}$	$\varphi_{e}^{CM} - \varphi_{pion}^{CM}$ before correction	$\varphi_{e}^{CM} - \varphi_{pion}^{CM}$ after correction
