Abstract
We present the Texas Survey of discrete radio sources between -35 degr ees.5 and 71 degrees.5 declination (B1950), which was carried out at 3 65 MHz with the Texas Interferometer during 1974-1983. The Survey list s accurate positions with internal errors of about an arcsecond, flux densities which for strong point sources have internal errors of about 1% and total errors of about 5%, simple structure models and indicati ons of spectrum and variability for 66841 sources. Results of comparis ons with other data are presented, and show that the Survey is 90% com plete at 0.4 Jy and 80% complete at 0.25 Jy, is nearly free from spuri ous sources, and has a lobeshift incidence which is reasonably describ ed by quality flags associated with each source.
