We examine the X-ray point source population and 2-10 keV luminosity for two galaxies with high star formation rates ( SFRs ) , NGC 4194 and NGC 7541 .
The X-ray point source luminosity function ( XLF ) for these two galaxies is consistent with the XLF found by Grimm et al .
( 2003 ) for a sample of star-forming galaxies .
Combining our results with a sample of galaxies with SFRs above 1 M _ { \odot } /yr , we find that the number of X-ray point sources above a luminosity of 2 \times 10 ^ { 38 } erg s ^ { -1 } is N = ( 1.8 \pm 0.4 ) { SFR } / ( M _ { \odot } yr ^ { -1 } ) .
This number is lower than previously inferred by Grimm et al .
based on a sample of galaxies with lower SFRs .
We find that the ratio of X-ray luminosity in the 2-10 keV band to SFR is L _ { X } / ( 10 ^ { 40 } erg s ^ { -1 } ) = ( 0.37 \pm 0.08 ) { SFR } / ( M _ { \odot } yr ^ { -1 } ) .
This value may serve as a calibration in attempts to use X-ray luminosity to measure the SFR of galaxies at cosmological distances .
The ratio of mass accreted onto compact objects versus mass used to form stars is near 10 ^ { -6 } .
This ratio may be useful in constraining population synthesis models of X-ray binary formation in actively star forming systems .
