Abstract
A 140 deg strip along the Galactic plane with the VLA has been surveyed for OH masers. Fifty OH masers, including 14 new sources, were detected. The masers have a very narrow distribution in Galactic latitude and are probably Population I objects. A study of the IRAS counterparts to OH masers from this and other surveys reveals a strong correlation between the infrared colors of OH masers and Galactic latitude.	Comments: Spectral type was set to: ""S"", where only one peak was found. ""D"", where two peaks were found. No velocities are provided. Sources are OH maser candidates.

Abstract

A 140 deg strip along the Galactic plane with the VLA has been surveyed for OH masers. Fifty OH masers, including 14 new sources, were detected. The masers have a very narrow distribution in Galactic latitude and are probably Population I objects. A study of the IRAS counterparts to OH masers from this and other surveys reveals a strong correlation between the infrared colors of OH masers and Galactic latitude.

Comments:
Spectral type was set to:
""S"", where only one peak was found.
""D"", where two peaks were found.

No velocities are provided.
Sources are OH maser candidates.

Type	Description
I	Oxygen-rich non-variable stars without circumstellar shells
II	Variable stars with "young" O-rich circumstellar shells
IIIa	Variable stars with more evolved O-rich circumstellar shells
IIIb	Variable stars with thick O-rich circumstellar shells
IV	Variable stars with very thick O-rich circumstellar shells
V	Planetary nebulae and non- variable stars with very cool circumstellar shells
VIa	Variable stars with relatively cold dust at large distances; a significant part of the stars is carbon-rich
VIb	Variable stars with relatively hot dust close to the star and relatively cold dust at large distances; Some of the objects have proven to be O-rich
VII	Variable stars with more evolved C-rich circumstellar shells
VIII	Different sort of objects
