Notes. Errors are 90% confidence level for one parameter of interest. The fit provides a 
for 3885 degrees of freedom, after the addition of a systematic error of 2%. The effective neutron star temperatures were not corrected for the gravitational redshift. Radii were computed using a 1.37 kpc source distance
