Unbiased X-ray sampling of stars within 25 parsecs of the Sun. Final Report

A search of all of the Einstein Observatory IPC and HRI fields for untargeted stars in the Woolley, et al., Catalogue of the nearby stars is reported. Optical data and IPC coordinates, flux density F sub x, and luminosity L sub x, or upper limits, are tabulated for 126 single or blended systems, and HRI results for a few of them. IPC luminosity functions are derived for the systems, for 193 individual stars in the systems (with L sub x shared equally among blended components), and for 63 individual M dwarfs. These stars have relatively large x-ray flux densities that are free of interstellar extinction, because they are nearby, but they are otherwise unbiased with respect to the x-ray properties that are found in a defined small space around the Sun
