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.
