Abstract:
The galaxy NGC6384 has been observed with an IPCS through Hα and
[NII] narrow-band interference filters for direct imagery with the
2.6-m Byurakan telescope. We studied the main physical parameters of
the identified 98 HII regions, their diameter and luminosity
functions, as well the [NII]/Hα ratio distribution.
Description:
The observations have been made with the CIGAL equipment which mainly
consists of a mainly focal reducer with IPCS and scanning Fabry-Perot
interferometer attached to the F/3.8 prime focus of the 2.6-m
telescope of Byurakan Observatory (Armenia) on September 7, 1985.

Note (1): The HII region positions were obtained as the pixel coordinates
of maximum flux, and these were referred to the center of the galaxy
determined from the pixel of maximum flux in the Hα image.
oRA is positive toward East, and oDE is positive toward North.
