Dear colleagues,
On behalf of the JMMC AMBER data reduction working group, I am pleased to announce the release of the version 3.0 of the AMBER data processing package.
You can find it on the JMMC website at: http://www.jmmc.fr/amberdrs together with an installation guide, a user's manual and demo data/script.
This release contains major modifications of the C-library which implements the AMBER optimized data reduction by Chelli, Hernandez Utrera, and Duvert (2009, A&A 502, 705). The release notes are available at this address:
http://www-laog.obs.ujf-grenoble.fr/twi ... _wrt_versi
The Yorick interface has evolved to be more user-friendly with a default data processing procedure. The User's Manual has been updated and contains most of the information needed by beginners.
If you have any question related to this AMBER Data Reduction Software release, please contact the JMMC User's Support
We wish you all the best,
F. Malbet, G. Duvert, F. Millour, J.-B. Le Bouquin, G. Mella

We are pleased to make the announcement that a new all-sky catalogue of computed stellar angular diameters (JSDC) is now available online on the Centre de Donnees astronomiques de Strasbourg (CDS) server : http://cdsarc.u-strasbg.fr/cgi-bin/Vizi ... rce=II/300
The present catalogue contains stellar angular diameter for about 38500 bright stars (Vmag < 12.2, Kmag <11.5) obtained from an automated SearchCal results aggregation on the whole sky. For each star are given, the value of the limb-darkened angular diameter computed using a surface brightness method as well as the values of the uniform disk angular diameters estimated for the photometric bands B, V, R, I, J, H and K.

The JMMC bad interferometric calibrators catalogue is now
available online on our server: http://apps.jmmc.fr/badcal/
Your feedback is very welcome in order to improve this first version and to feed it.

If you do not see any changes after some clicks into the filechoosers, some users get a better display using a different color map.
cp .../yorick/g/heat.gp $HOME/.gist/gray.gpAfter this change, the selected files should be underlined or with a different background color.

If you encouter the error "another instrument with same name already exists", you probably have built one settings with multiple oifits files. It is actually one limitation of the internal engine which should be fixed soon. To be able to fit such settings files, you actually need to modify manually the name INSNAME keywords of each given files. It must be done in all the OI_VIS, OI_VIS2, OI_T3 plus the corresponding OI_WAVELENGTH tables. Each values must be different to be fitted by LITpro. Apologize for the actual limitation. We are working on this issue for the next releases.
An alternative is to merge multiple oifits files into a single file. This can be done using the oifitslib software available at the following address: ftp://ftp.mrao.cam.ac.uk/pub/jsy1001/oifitslib/oifitslib.tar.gz

If you encounter this problem for the "plot 1D chi2" and "plot 2D chi2" actions, you probably have bounds problems. Please check that your parameters have compatible minimum and maximum limits.
This bug affects the Version 1.0.4.

During the last IAU conference in August 2009, the Optical and
Infrared Interferometry Commission (C54) raised a few questions
(get the whole story on http://olbin.jpl.nasa.gov/iau/2009/index.html).
One of them was :
"Is there a command line tool to throw at an OIFITS file to do a
simple uniform disk fit?"
Well, now, there is. Just "call Iper"
This simple tool allows you to rapidly see if your set of squared
visibilities is fitted or not by a uniform disk.

Some JMMC members will attend this school and provide support for training infrastructure. Hope to meet you over there.

One router will me moved onto the university network and could make the jmmc webservers unreachable. The service outage is programmed on Monday March 29, from 17:00 to 18:00 GMT.
Sorry for the inconvenience.
