J/ApJ/656/255  Arecibo methanol maser Galactic Plane Survey   (Pandian+, 2007)

The Arecibo methanol maser Galactic Plane Survey. I. Data. Pandian J.D., Goldsmith P.F., Deshpande A.A. <Astrophys. J., 656, 255-274 (2007)> =2007ApJ...656..255P
ADC_Keywords: Surveys ; Masers ; Radio sources Keywords: masers - radio lines: ISM - stars: formation - surveys Abstract: We present the results of an unbiased survey for 6.7GHz methanol masers in the Galactic plane carried out using the 305m Arecibo radio telescope. A total of 18.2deg2 was surveyed with uniform sampling at 35.2≤l≤53.7, |b|≤0.41. The large collecting area of Aecibo and the sensitive C-Band High receiver allowed the survey to be complete at the level of 0.27Jy, making this the most sensitive blind survey carried out to date. We detected a total of 86 sources, 48 of which are new detections. Most of the new detections have a peak flux density below 2Jy. Many methanol masers are clustered, reflecting the formation of massive stars in clusters. Description: The observations were made between 2004 June and 2006 March using the 6-8GHz (C-Band High) receiver at the 305m Arecibo radio telescope. File Summary:

Note (1): Notes as follows: a = This source is identified by different (l, b) coordinates in Pestalozzi et al. (2005, Cat. J/A+A/432/737) due to incorrect coordinates being quoted for the IRAS source toward which Szymczak et al. (2000, Cat. J/A+AS/143/269) detected methanol maser emission. We relabel this source using our coordinates, which are more accurate for the methanol maser than the coordinates of the IRAS source. b = This source was detected at the edge of a data cube and could not be detected in successive observations of the region. Hence, the actual coordinates of this source could be different from those quoted here. c = The coordinates of this source detected in the Onsala Survey (which is not yet published in a refereed journal) and listed in Pestalozzi et al. (2005, Cat. J/A+A/432/737) are very different from our coordinates. We think that this could be due to a software problem, similar to the one giving rise to incorrect coordinates for IRAS sources published in Pestalozzi et al. (2005, Cat. J/A+A/432/737). Hence, we label this source with (l, b) determined from our coordinates.
