RESUMEN
]]> En este artículo usamos las observaciones presentadas en Rozas (2007) de la galaxia NGC 5055 en las líneas Hα; y Hβ, junto con observaciones CCD con filtros estrechos en las líneas [OII], [OIII], [SII] y S[III] para calcular las anchuras equivalentes, excitación, grados de ionización, parámetros de ionización y metalicidades de las regiones catalogadas en Rozas (2007).
ABSTRACT
In this paper, using CCD observations of the galaxy NGC 5055 in the emission lines of Hα and Hβ (Rozas 2007), together with CCD observations in the narrowband filters of [OII], [OIII], [SII], and S[III] lines we have calculated the equivalent widths, excitations, ionization hardness, ionization parameters and metallicities for the regions catalogued in Rozas (2007).
Key Words: galaxies: individual (NGC 505) — galaxies: kinematics and dynamics — galaxies: spiral
