Table 3
Least-squares fits to the bright tail of the binned LF in the six redshift bins of Fig. 6.
| z | Log LX | γ |

||
| < 0.5 | > 43.5 | −1.3 ± 0.1 |
| 0.5 <z< 1 | > 44 | −1.5 ± 0.1 |
| 1 <z< 1.5 | > 44 | −1.8 ± 0.2 |
| 1.5 <z< 2 | > 44.5 | −2.0 |
| 2 <z< 3 | > 44.5 | −1.8 |
| 3 <z< 4 | > 44.5 | −2.3 |
Notes. The first column identifies the redshift bin; the second column shows the luminosity range used for the fit; the third column gives the fit parameter γ for the linear formula Log(dΦ/dLogLX) = γ Log LX + c. The bins with z> 1.5 do not show an error for γ because only two data points were available for each fit; however, an error of the same order of that of the previous bins may be reasonably assumed.
