Description:
    Using the KOSMA 3-m telescope we have made observations of the
    12CO(J=1-0), (J=2-1) and (J=3-2), and the 13CO(J=1-0) and (J=2-1)
    transitions of the high latitude cloud MBM 32.
    The backend consisted of a Medium Resolution (channel width 167kHz;
    MRS), or a High Resolution (channel width 38.6kHz; HRS)
    acousto-optical Spectrometer.
    The following tables contain properties of clumps derived from the
    maps, assuming Gaussian clump parameters from the
    12CO(J=1-0) MRS data (Table 3)
    12CO(J=1-0) HRS data (Table 4)
    12CO(J=2-1) MRS data (Table 5)
    13CO(J=1-0) HRS data (Table 6).
    We distinguish between different velocity components.

Note (1): Vlsr interval is coded as follows:
       1:   Vlsr>2km/s
