Abstract:
We analyze the Halpha emission of the star-forming region NGC 6334 and
NGC 6357 with the aim to precise/determine the nature of the HII
regions.
Description:
The FITS files contain the data cubes corresponding to the optical
Halpha line, covering the regions NGC 6334 and NGC 6357. They were
taken in 1994, using a scanning Fabry-Perot interferometer mounted on
a 36cm telescope located at La Silla-ESO. The pixel size is
9.26-arcsec and the scanning step is 4.8km/s. The velocity are Vlsr
velocities.
