Description
Multiwavelength information is crucial for a complete understanding of the Universe. Therefore, SPIDERS (Spectroscopic Identification of ERosita Sources) selected objects identified in X-rays with eROSITA to be observed in the optical domain by SDSS-V. We present the Data Level 1 of the collaboration between SDSS and eROSITA, in which we make available the main features of sources observed in optical and X-rays, such as position, spectroscopic redshift, object type, class, stellar templates, public photometric data, X-ray morphology, X-ray flux and likelihood, among other parameters. This catalog contains information on clusters of galaxies, quasars, AGNs, stars, and compact objects. It should be uploaded frequently as more Internal Product Launches of SDSS are released. Many scientific questions can be answered based on the statistics of this large sample, which can be of interest to the whole SDSS-eROSITA community.
