Description
The primary mission of eROSITA is to detect clusters of galaxies in order to measure cosmological parameters. In order to build a cosmological model, we also need well-characterized X-ray mass measurements. Therefore, detecting clusters and measuring their properties is therefore a very important aspect of eROSITA data analysis. We will describe how clusters are detected in the eROSITA sky survey by the standard detection pipeline. Measuring the properties of clusters requires a combination of imaging and spectral analyses. We will discuss the MBProj2D (Multi-Band Projector in 2D), a Python package that simultaneously models clusters in multiple energy bands to measure radial profiles of their physical properties. We will also discuss the accurate spectral fitting of clusters.
