Abstract:
    Using the 13.7m telescope of the Purple Mountain Observatory (PMO), a
    survey of the J=1-0 lines of CO and its isotopes was carried out on 98
    methanol maser sources in January 2008. Eighty-five sources have
    infrared counterparts within one arcmin.

Description:
    The observations were made in January 2008 with the 13.7m telescope of
    PMO at Qinghai Station. The 12CO, 13CO and C18O (J=1-0) lines
    were observed simultaneously by a superconductor receiver.
