V/68A       Stellar Maser Observations (Benson+ 1990)

A Catalog of Observations for Stellar Masers Benson P.J., Little-Marenin I.R., Attridge J., Blais K., Randolph D., Woods T., Rubiera M., Keefe H. <ApJS, 74, 911 (1990)> =1990ApJS...74..911B
ADC_Keywords: Masers ; Stars, masers Description: This catalog contains about 2958 stellar sources. For the searching of the maser emission of the sources listed, 368 were detected in H2O, 209 in SiO, and 713 in OH. In the catalog, one can find information about the stars including alternate names, the 1950 epoch position, velocity (LSR), spectral type, variability type, and period, as well as the references for both the detections and nondetections for each of the three molecules. In this catalog, Table 1 lists all the sources in right ascension order, Table 2 lists the references for all the maser observations for each source, and Table 3 lists the references in code order, i.e., in chronological order.

Remarks and Modifications: For the 2958 stellar sources listed in this catalog, 1769 had been searched for H2O emission. and it was detected in 368 (21%) of those observed; 639 sources had been searched for SiO emission with detections in 209 (33%); and 2253 sources had been searched for OH emission with detections in 713 (32%). Because strong biases found in the data the percentages should be interpreted with caution. For detailed bias information, please consult Benson et al. (1990).
