HII Region Analysis in Dwarf Irregular Galaxies:
TheSlog & HIIphot
Abstract
We have CTIO 4-m telescope + Mosaic wide-field CCD camera images taken
in UBVRI and Halpha, [SII], and [OIII] of three Local Group dwarf Irregular
galaxies: NGC 6822, WLM, and Phoenix, taken as part of the Survey project.
As a step towards understanding the mode of star formation in these galaxies,
we are employing an automated method to study the HII regions. A multi-step
project, we are currently investigating the differences between HII region
analysis done in a 1988 study of NGC6822 and the automated analysis, and
developing a reference guide for Mosaic reductions. A complete sample of
HII regions would be used to compare the properties of the HII regions
(through luminosity functions and distribution of morphologies) with those
in other Local Group galaxies.
