J/AJ/92/787         Outer galaxy VLA survey                  (Fich 1986)

A complete VLA survey in the outer galaxy. Fich M. <Astron. J. 92, 787 (1986)> =1986AJ.....92..787F (SIMBAD/NED BibCode)
ADC_Keywords: Radio sources ; Radio lines ; H II regions Abstract: The VLA has been used to make a "snapshot" survey of all radio continuum sources stronger than 0.3Jy at 21cm, smaller than 2arcmin, and in the area in the sky defined by l=93° to 163°, b=-4° to +4°. These objects were observed at 6 cm with a resolution of 4 arcsec and a sensitivity of 1mJy. A second set of observations were carried out to determine the spectral indices of all objects not resolved in the 6 cm survey. These objects were observed at a wavelength of 2cm with resolution and sensitivity similar to the 6cm survey. The purpose of this study was to identify objects within the disk of the outer parts of our galaxy. It is shown that the current lists of identified H II regions in this area are better than ∼70% complete for H II regions in the Perseus arm or closer. The only supernova remnants remaining to be discovered in this field are either extremely young, and therefore possibly radio quiet, or they are among those objects too extended to be observed at the VLA in this survey (i.e., greater than 2arcmin in diameter).

VII/20) W refers to Westerhout (1958BAN....14..215W) SNR refers to an unnamed supernova remnant Note (2): n: no detection, c: confused, v: very strong,confused, w: very weak o: outside of 2cm field, b: observed wrong position e: flux estimated from maps, else from Kallas & Reich (1980A&AS...42..227K) catalog Note (3): Comments, including other names for the object (BFS refers to the catalog of Blitz et al., 1982, Cat. VII/50) and details about the structure seen, size scales, and type of object (e.g., HII means H II region). If no size is given, the object was not resolved. Note (4): *: a correction has been applied. The 4.89GHz fluxes have been corrected for primary-beam attenuation (PBAF) and bandwidth smearing (BWSAF) as follow: KR22 : PBAF = 1.83, BWSAF = 2.3 KR71 B: PBAF = 1.21, BWSAF = 1.33 KR71 C: PBAF = 1.18, BWSAF = 1.28 KR71 D: PBAF = 1.14, BWSAF = 1.22 S167 : confused with Cas A SNR KR93 B: PBAF = 2.13, BWSAF = 2.83 KR100 : PBAF = 1.25, BWSAF = 1.39 KR128 : PBAF = 1.14, BWSAF = 1.22 KR147A: PBAF = 1.25, BWSAF = 1.40 KR147B: PBAF = 2.04, BWSAF = 2.70 KR155 : PBAF = 1.12, BWSAF = 1.19, 2 jets and halo, ext 90"x30" KR178 : PBAF = 1.15, BWSAF = 1.24 KR186 : core + 2 jets, 35"x10" KR193 : PBAF = 1.12, BWSAF = 1.17 KR204 : can not separate two components at 2cm KR212 : PBAF = 1.13, BWSAF = 1.18, over-resolved, see text KR221 : PBAF = 1.28, BWSAF = 1.44 KR228 : PBAF = 1.57, BWSAF = 1.91, flux missing KR235A: PBAF = 1.15, BWSAF = 1.22 KR235B: PBAF = 1.25, BWSAF = 1.39
