Galactic Requirements

Data

The status of data is described below.
Most of the cases use data which are already available to Aladin or are about to be. These are, in increasing order of importance:

1. Optical spectra for identifying Halpha, Li etc; (probably not available)
2. XMM multi-energy images (possibly) or spectra (probably not suitable at this stage)
3. SuperCosmos Halpha images (possibly)
4. Galactic Plane surveys (radio, CO, etc.) held by CADC (already available on manual load, nice trees for datacubes)
5. ISO data - spectra and images already available.

We need timescales for the possibles and debugging....

ISO spectra

1. LWS available, minor issues being solved.
2. Ivo Busko has modified Specview to enable them to be displayed reasonably;
3. The SFR science case involves measuring the flux at 3 spectral points; this can also be done in Specview now;
4. The science case ideally involves VOTable output from spectral measurements into VOPlot, see below

Tools

1. Current AVO demonstration model of Aladin including links to VOPlot, SED tool and ACE
2. New Aladin capabilities including astrometric aligment and displays using native flux density units - would be used but not essential
3. Spectral tool - this can:
   1. Measure the flux density at various wavelengths;
   2. Write this out as ascii
   3. Possibly identify lines in ISO spectra
4. Spectral tool/VOPlot - the scenario for extracting ISO colours from LWS spectra envisages writing measurements out as

Can work with whatever is available - great progress already in Specview and with ISO data (and XMM images were already there) and with the CADC data cubes!
