cds-question@unistra.frinterstellar-masersinfrared-sourcesspectroscopyradio-astronomyWe have performed targeted surveys for 22GHz H_2_O and 43GHz SiO maser emission in Galactic center OH/IR stars using the Very Large Array. Some of the detections have been used in a previous paper to investigate the possibility of measuring milli-arcsecond accurate positions (to obtain stellar proper motions) in the Galactic center. Here we report on the detection of at least 25 H_2_O masers and 18 SiO masers associated with stars within 2{deg} and 15' of Sgr A*, respectively. This survey has more than doubled the total number of proper motion candidates to at least about 50 stellar objects.2002A&A...391..967Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/391/967CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/368/845 : Arcetri Catalog of H2O maser sources.
