A composite large-scale CO survey at high galactic latitudes in the second quadrant

Surveys undertaken in the 2nd quadrant of the Galaxy with the CfA 1.2 m telescope have been combined to produce a map covering about 620 deg 2 in the 2.6 mm CO(J=1→0) line at high galactic latitudes (16°≤b≤44°, 117°≤l≤160°). There is CO emission from molecular cirrus clouds in about 13% of the region surveyed. The CO clouds are grouped together into three major cloud complexes with 29 individual members. All clouds are associated with infrared emission at 100 μm, although there is no one-to-one correlation between the corresponding intensities
