Dear Collegues
After receiving some feedback to the email reproduced below I propose the
following
agenda for the theory session in Kyoto, which is scheduled for wednesday
morening.
First we'll have some presentations, each about 15 minutes:
These presentations about cover the subjects proposed in the email below,
with some emphasis
on theory spectra, which clearly is of interest for a number of people.
I propose to have discussions about these subjects in the remainder of the
session.
In particular we should discuss:
I hope that members of working groups can attend these discussions.
Please send any comments to the mailing list.
Thanks and see you in Kyoto
Gerard

> 1. Availability of simulations online.
> One of the goals of the theory group is to promote the publication of
> simulation results according to standards developed in the IVOA working
> groups. A prerequisite for this is that simulation results are actually
> available online in some form. We need to have examples of this and look
at
> different ways in which simulations results are currently made available
> online, which kinds of simulations are there, what services are provided
> for accessing them. From this we can select a first category for which
> we can look at ...
>
> 2. IVOA compatible publication of simulations.
> We should choose a small set of existing examples which we want to further
> develop and propose as use cases for the standards process. The further
> development
> should consist of work along the lines of the IVOA working groups. In
> particular:
> we want it to be possible to register data sets and services in an IVOA
> registry,
> we want to be able to describe simulations according to IVOA standard data
> models,
> we want to come up with standards for data exchange formats (VOTable?,
UCD),
> we
> may want to see where the VO query language could be implemented and maybe
> there
> are some standard data access services we can define. Some proposals have
> been
> made, for example Laurie Shaw’s contributions on a simulation data model
and
> a
> list of UCDs for simulation data. It would be good if these and other

so
> that we may come up with some proposals we can make to the other working
> groups.

> 3. Theory/observational interface.
> As has often been stated before, the holy grail of the theory work in the

theorists

> a simulation and produce mock images that can be directly compared to real
> observations. GAVO is collaborating with a number of groups who have
created
> such tools which GAVO is publishing on its webpage. The planck simulator
is
> one, others are observations of hydro simulations of galaxy clusters and
> mock
> pencil beams through a large scale cosmological simulation. Based on the
> various examples, it seems to me that this virtual telescope concept
offers
> a nice opportunity to come up with a modularized design specification that
> allows explicit interoperability between components designed and
implemented
> by experts on their field. I am writing up a proposal on this that I will
> submit to the mailing list in the coming week (I hope).
