Pre release of the Aspro2

JMMC Team — Mon, 06 Sep 2010 18:43:00 GMT

Dear Colleagues,

We are pleased to announce the availability on the JMMC webpage of a pre-release version of Aspro2, our new observation preparation software.

Aspro2 provides the user with a highly dynamic graphical interface, does not depend on any network connection to work, and has sufficient new interesting features (such as creating Observing Blocks for VLTI and CHARA, or its ability to save/restore your work in progress), that we consider it would be useful to share it with you, even if it is still a work in progress.

A feature comparison between Aspro software versions is also available on the JMMC webpage to see main differences : for example, Aspro 2 does not have a visibility explorer yet.

As usual, we will be more than happy to get comments and/or bugs, especially through the new feedback mechanism present in Aspro2.

Best regards,

On the behalf of the JMMC Aspro Group,
Gilles Duvert & Laurent Bourg�s

Aspro updated to Period 87 values

JMMC Team — Wed, 01 Sep 2010 13:15:45 GMT

As the title says, Aspro (one should say 'old Aspro', since Aspro2 is now in prerelease) has been updated to cope with baselines, limiting magnitudes, etc... described in the ESO call for Proposal for Period 87. It retains however the previous setups back to period 84.

JSDC - a new catalog of computed stellar angular diameters

JMMC Team — Mon, 28 Jun 2010 15:59:10 GMT

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.

BadCal online

JMMC Team — Mon, 14 Jun 2010 14:08:00 GMT

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.

Invisible selection for the color of the file browser

JMMC Team — Mon, 10 May 2010 07:34:23 GMT

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.gp
After this change, the selected files should be underlined or with a different background color.

"another target with same name already exists" error with LITpro V1.1

JMMC Team — Wed, 14 Apr 2010 12:11:33 GMT

If you encouter the error "another target 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

ERROR : ghostscript bounding box not found Can't get chi2map plot

JMMC Team — Wed, 14 Apr 2010 11:44:32 GMT

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.

Iper: a simple tool to fit OIFITs data with a uniform disk

JMMC Team — Thu, 25 Mar 2010 16:35:18 GMT

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.
