Utilizing only near on-axis, bright X-ray sources (to avoid problems caused by incompleteness and the Eddington bias), we derive the Log(N)Log(S) relation in soft (0.5-2 keV) and hard (2-8 keV) energy bands. ... We have also fitted our H band Log(N)-Log(S) in the flux range 5 x 10-15 to 2 x 10-13 erg sec-1 cm-2. ... Figure...

... By comparison, old elliptical galaxies have a wide range of Lx(gas) and some of them (e.g., group or cluster dominant galaxies) have Lx(gas) 10 or 100 times higher than Lx(LMXB). One of the key observables to address the age effect is the abundance ratio of Fe to elements, b ecause of different pro duction yields of SNe Ia and I I. In the merger scenario of young elliptical galaxies, we would exp ect an enrichment of -elements from SN I I, asso ciated with the recent star formation. ...
