Figure 1: IRAM 30-m telescope beam pattern
calculated from scans across the limb of the Moon after the July 1997
surface re-adjustment. The heavy lines show gaussian approximations to the
main beam and error beams. For each pattern, the profile is normalized to
half-width of the full beam (from Greve, Kramer and Wild 1998, A&A Suppl.
133, 271; see also this Newsletter below).
