면천체(EXTENDED OBJECTS)에 대한 긴 슬릿 분광관측 연구

LONG-SLIT SPECTROSCOPY FOR EXTENDED OBJECTS

We will discuss two-dimmensional spectrophotometry including long-slit spectroscopy and narrow-band imaging. The basic principles, applications, and techniques of observations and data reduction of spectroscopy and spectrophotometry for extended objects are described. This discussion will focus on practical long-slit spectroscopy using a Cassegrain spectrograph attached with 2 or 4m class telescopes and on imaging spectrophotometry using narrow-band interference filter sets. We will discuss scientific applications.
