Scientific paper

The Two Micron Galactic Survey (TMGS) is the most sensitive large scale point source near infrared survey of the Galactic Plane yet attempted. The Galactic plane has been drift-scanned in several regions over the areas -5 deg less than l less than 30 deg, absolute value of b less than or equal to 15 deg and 30 deg less than l less than 180 deg, absolute value of b less than or equal to 5 deg. The survey is complete in the areas covered to magnitude mk = +9.8. So far, a total area of 255 square degrees has been mapped and 500,000 objects have been detected, the majority of these in the Galactic plane and with no visible counterparts. In this contribution, we use data from the TMGS to probe the star distribution within the Galactic disk.
