Welcome. Discussion on the agenda for this week. (Harm)

Theme of the day: 

Status of the data reduction, calibration and croscorrelation 
(organizer: Guy Simon)

- Isogal data reduction procedures and cross-identification methods
- Something about the photometric quality  (Frederic)
- Organization of the ISOGAL-DENIS point source catalogue to be
   published (Alain).

Items to be discussed:
- Raster calibration using Fouks-Shubert transient correction, 
   projection, psf-fitting 
   (Joris, Frederic, Cecile)
- Reproducibility of photometry (Martin C.; Martin G.)
- Use of LWS- and CAM-// mode as complementary data sets
   (Martin B.)
- Combining DENIS, 2MASS, MSX with ISOGAL (Martin C.; 
    Martin G.)
- Confusion limited source surface densities (Martin C.)
- Will there be an overall ISOGAL catalogue or set of catalogues? 

Welcome party with cheese and wine
