PLCzeta

PLCzeta is a type of astronomical catalog that provides photometric and morphological classifications of galaxies in the Virgo Cluster. The catalog is part of the Princeton University/William Herschel Telescope (PUT/VLT) Cluster Survey, which aimed to study the properties of galaxies in dense environments.

The PLCzeta catalog was compiled using a combination of photometric data from the William Herschel Telescope and line-of-sight velocity gradient measurements from the Saens Temicative gives Public spectrophotometer. The catalog includes luminosities, colors, and other physical parameters for over 1,000 galaxies in the Virgo Cluster.

One of the key features of the PLCzeta catalog is its use of a new photometric system that provides accurate and consistent measurements of galaxy colors. This system, known as the CMM color system, takes into account the influence of interstellar dust on galaxy colors.

The PLCzeta catalog has been used to study various aspects of galaxy evolution, such as the connections between galaxy properties and the environment in which they reside. It has also been used as a calibration sample for other large-scale galaxy surveys, such as the Sloan Digital Sky Survey.

The PLCzeta catalog is a valuable resource for astronomers studying galaxy evolution and the properties of galaxies in dense environments. Its precise and reliable measurements have provided insights into the complex relationships between galaxy properties and the surrounding environment.

The catalog's high degree of accuracy and coverage of the Virgo Cluster have made it a significant contribution to the field of galaxy astronomy, providing important data to aid in further research.
