| under development, RMM 2005/03/30 {{{ (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 == Mirroring between IRAM Grenoble ( http://www.iram.fr ) and Granada( http://www.iram.es/ ) websites sometimes takes several days to update. (2003-07-01) == Other Items == OK Back to top == Udates/History (in reverse order by date!): == 2004-12-01 AW 2004-07-24 RM 2004-03-24, 25 HU 2004-01-17 AW 2003-11-12 HU 2003-09-25 MR 2003-09-08 HU 2003-08-20 HU 2003-08-05 AS 2003-07-09 RM 2003-07-01,04/5, 7 HU 2003-06-08, 09 HU 2003-04-22, 26 HU 2003-04-06 AS 2003-03-31 HU 2003-03-20 RM 2003-02-11 AW 2003-01-10, 2003-01-17, 2003-02-05 RM 2003-01-14 TG 2003-01-03, 06 HU 2002-12-31 HU 2002-12-21, 22 HU 2002-12-19 RM 2002-12-13, 14, 15, 16 HU 2002-12-11 RM 2002-12-05 TG 2002-11-27 RM 2002-11-05 AW 2002-10-18 DJ 2002-10-15 DJ 2002-10-09, 12, 14 HU 2002-10-08 AW 2002-09-27 TG 2002-09-26 DJ 2002-09-23 AW 2002-09-11/12, 17 HU ...

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. For more details and further topics, see the MoinMoin page. ---- You can edit any page by pressing the link at the bottom of the page. Capitalized words joined together form a WikiName, which hyperlinks to another page. The highlighted title searches for all pages that link to the current page. Pages which do not yet exist are linked with a question mark: just follow the link and you can add a definition. To get an overview over this site and what it contains, see the SiteNavigation page. To learn more about what a WikiWikiWeb is, read about MoinMoin:WhyWikiWorks and the MoinMoin:WikiNature. Also, consult the MoinMoin:WikiWikiWebFaq. ---- Interesting starting points: * RecentChanges: see where people are currently working * HelpForBeginners: to get you going * WikiSandBox: feel free to change this page and experiment with editing * FindPage: search or browse the database in various ways * SyntaxReference |
