Proposal Abstract

The proposed observations consist of 2 experiments: NGC7538 and NGC6334N. These sources are caracterized by not only OH maser emission but also H2O and Methanol lines. The sizes of OH maser spots on this sources have not been measured previously with VLBI techniques but both sources have been found to be unresolved on baselines of over 7000 kms. Of the few OH maser candidates for VSOP's ultra-high spatial resolution these sources can reveal intrinsic size and structure of OH maser spots, not broadened by interstellar scattering. The size and brightness temperatures of the spots measured with no scattering effects would be greatly useful for the study of the inter- stellar medium and the masing process itself.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that many proposals were reduced in extent by the Scientific Review Committee (e.g. by reducing the number of experiments), however the Cover Sheets contain the full proposal as submitted. Also note that AO2 proposals were submitted in May 1998, and information such as affiliations and contact details has changed for some proposers since that time. The Cover Sheets (and the details on this page, which were derived from the Cover Sheets) may therefore have changed.
