Moreno(1) report:\n  (1) IRAM    (Grenoble, France)\n  (2) IAA-CSIC  (Granada, Spain)\n  (3) LAEFF-INTA (Madrid, Spain)\n\nWe have observed the GRB 010222 radio counterpart with the Plateau \nde Bure Interferometer (PdBI) in a compact five antenna configuration\non February 24.94 - 25.11 UT, using the position from Henden et al. \n(GCN 967).  Weather conditions were good for wavelengths of 3mm but \nmarginal for 1mm.  The flux calibration was relative to CRL 618 \n(1.55 Jy at 3mm and 2 Jy at 1mm) and is accurate to about 10%.\n\nThe source was not detected.  UV fits on the phase center give the \nfollowing upper limits (fit errors are one sigma) :\n\n  93.109 GHz : -0.49 +- 0.32 mJy/beam  \n 232.032 GHz : -0.09 +- 1.6  mJy/beam\n\nThe results have been corrected for atmospheric decorrelation.\nSynthesized beams were 9.3\" x 5.2\" at PA -57 degrees and 3.6\" by 2.3\" \nat PA -46 degrees, respectively.  No bright sources were detected \nwithin the primary beam.",
