Table 6:

Field by field comparison of the slopes above and below the break luminsoty ( $L_{\rm b}$ ) for the CLFs created from freely fit spectra and the CLFs of luminosities derived from fixed models. $L_{\rm b}$ is set to 10³⁶ erg s^-1, the slopes are for the CLF above and below $L_{\rm b}$ . Data for the bulge of M 31 comes from Shirey et al. (2001) where the break is $2.5 \times 10^{36}$ erg s^-1.
