AMBER Scientific Workshop (Grenoble, 7-8 Mar 2007)
First publication : 3 March 2007, publicated: Monday 27 August 2007, by Fabien Malbet

NEW: presentations and video clips are now available

Rationale: AMBER/VLTI has now been offered since October 2005 to the ESO community. We would like to gather the astronomers who have obtained AMBER data in order to publicize the various results and share our common experience on the instrument. This will also be the opportunity to give some information on the current status of the instrument. This workshop will last 1.5 day and will be followed by the meeting of the AMBER science group.

Organizer: F. Malbet, AMBER Project Scientist, together with the AMBER science group (SGR)

Venue: Laboratoire d’Astrophysique de Grenoble (Grenoble, France) from Wednesday 7 March 2007 at 9:00am to Thursday 8 March 2007 at 14:00pm.

Practical information:
- Hotels: see the list of hotels. There is also the Hôtel Ibis Université which is located on Campus on the A/C tram line which might be an interesting solution a little bit ex-centered compared to Grenoble downtown but certainly more quiet.
- Food: see the restaurants and bars section on the IAUS243 web site.

Financial support:
- We have limited resources to help young researchers to participate to this workshop. Please send an email to F. Malbet. before Friday 2 March 2007.
- We plan to have a buffet for Wednesday and Thursday lunches.

Note on limiting magnitude on FINITO in P80 CfP
13 March 2007, by Jörg-Uwe Pott

Since we discussed at the workshop the limiting magnitude of using FINITO+VLTI in the current ESO-CfP (is the limit H=3 referring to total flux (due to IRIS) or correlated flux (due to FINITO itself)), I posed this question to ESO to clearify the situation.

Jörg-Uwe Pott.

In the actual CfP is written (p.37, Sect.6.12.3) that for the use of FINITO, the ’limiting correlated magnitude’ is H=3. On the other hand the H=3 limit appear to come from IRIS (to be used in fast mode to use FINITO). That would mean: H=3 is a ’total flux limit’, instead of the given ’correlated flux limit’. This can be important, since the target stars are nearby and typically resolved.
With a total flux limit of H=3 and a minimum visibility of 15% (as given in the actual CfP), you would increase the number of targets.

ESO clearification for the actual period

In principle it is IRIS stopping to go fainter on FINITO but we were only successfully [tracking] fringes [on resolved sources] at 15% on a <1 Hmag source. [...]

Thus the statement of "correlated magnitude" is correct and possible after more standard operation on a much larger sample of targets we will be able to possible create some sort of lookup table for Visibility vs H magnitude as it seems that the constraints are not simply the 2.5*log(Vis) if you really want to be accurate.

So to conclude we offer it with the correlated limiting magnitude of 3 and the minimum V of 15% and most probably for the coming periods we will be able to improve on these numbers but for now these numbers stand.
