Description :

This record presents observations conducted with the IRAM 30m telescope for the field G202+02, a filament part of the Monoceros OB 1 molecular complex. The observations are composed of on-the-fly maps of the rotational emissions of 12CO, 13CO, C18O and N2H+ (J=1-0), as well as CS (J=2-1). The raw data will be available from the IRAM archive after the proprietary period. This record points to reduced and derived data, including data cubes for each detected transition and column density maps.

Discipline :

astronomy & astrophysics (sciences of the universe)

Keywords :

dense interstellar clouds, interstellar filaments, interstellar molecules, millimeter astronomy, star formation
