{{{ (Date 2004-12-01) System - General NORMAL OPERATION Antenna OK Wobbler Avoid wobbler throw of 120"; with a throw of 120" the specification of a phase time may not work properly. With a throw of 119 or 121 is should be OK. (2003-07-09) Results from first pointing after unlocking the wobbler can be wrong! Usually it's sufficient to ignore the first pointing and repeat the pointing (2003-07-09) Wobbler rotation implemented. Current range: +/- 60deg (2004-12-01 AW) Pointing Model heterodyn: OK (last model update: 2004-11-17 ). bolometer: OK (last model update: 2004-11-02 ). Operator/AOD: Check regularly that automatic P4 P5 is working (2002-12-13). Narrowband continuum pointing (for SiO masers) is out of service! (2003-07-09, 2003-07-30) SIS Receivers A, B, C and D receivers are aligned within 3", checked (2003-09-24) Calibration Tcold temperatures have been checked by receiver group. New scaling factor of 1.0 has been implemented into obs. Obs Tcold should be ok (2004-01-17) Pointing and Flux monitoring with SIS receivers: Continuum instability ("ripple") can occur with all receivers, making pointing and focussing difficult. In general some receivers are better then others in this respect as summarized here: A100 generally OK for pointing. (2003-11-12) B100 OK, will be replaced (2003-11-12) C150 often bad for pointing, ripple. (2002-07-16) D150 generally good performance for pointing.(2002-07-16) A230 often unstable, bad for pointing and flux monitoring. (2003-11-12) B230 OK, will be replaced (2003-11-12) C270 very bad for pointing at 265 Ghz. (2002-07-16) D270 can be unstable and difficult for pointing. (2002-07-16) HERA pointing difficulties using beam switch mode - total power mode gave better results (2004-01-17) HERA Second polarization installed. One blind pixel. No SSB tuning tables except for few standard frequencies. Sideband rejections not determined (2004-12-01 AW) Watch the computer control of the derotator closely (2002-12-22). Make sure the derotator tracking is stopped after observations, i.e, set to zero degrees in "frame". With VESPA, only two spectra per pixel can be used. Bolometers Mambo II is installed and ready for operation (AW 2004-12-01) Backends 256 MHz shift in 100kHz FB header (AW 2004-12-01) Software and/or hardware problem in the 1MHz FB - problem is currently investigated (AW 2004-12-01) Spikes in VESPA at intersection of different units (AW 2004-12-01) Computer/Software mrt-lx2 has a different "distribution" (Debian) than most other of our Linux systems. If you have problems with specific software try to use mrt-lx3 instead, which has an older version of SUSE Linux! (2004-03-24) Mirroring between IRAM Grenoble ( http://www.iram.fr ) and Granada( http://www.iram.es/ ) websites sometimes takes several days to update.

This wiki can also link to InterWiki space. MoinMoin is a Python Wiki:WikiClone, based on Wiki:PikiPiki. The name is a common German slang expression explained on the MoinMoin page. If you run a Wiki using MoinMoin, please add it to the MoinMoin:MoinMoinWikis page. Contributed code is on the MoinMoin:MacroMarket, MoinMoin:ActionMarket and MoinMoin:ParserMarket pages.
