ROSAT Observations of Symbiotic Binaries and Related Objects

We present X-ray observations of 217 confirmed or suspected symbiotic binaries with the ROSAT PSPC during the all-sky survey and 129 archived pointings. A table lists 3σ upper limits or detected count rates for survey and pointing observations (available for 46 objects) plus a collection of UBVJHK brightnesses, stellar types, outburst status, and structure (jets, ejecta, winds, clouds). The detection of 28 symbiotics (21 in survey) will be handled in greater detail in a forthcoming paper.
