Abstract
Systematic observations in the near-infrared on the TST-2 solar tower telescope of the Crimean Astrophysical Observatory began in 1999 and continue until now. During this time, unique observational material has been accumulated that allows us to analyze the evolution of coronal holes, filaments and active regions. Due to the fact that during this time the observational process has been repeatedly modernized with varying degrees of complexity, and changes have been made to the processing programs, we have several series of spectroheliograms of different types. The last stage of modernization, in particular, concerned the creation of new software, with the possibility of stream processing of observation results. This allowed us to systematize the work to unify the presentation of our data. In this paper, we present the updated database. The structure of the database, access to its elements, and examples of comparison of solar disk maps from our database with images of the Sun in other spectral lines and synthesized by different algorithms are discussed. The unified database is a convenient tool for uniform visualization of observational material obtained over more than two solar cycles. It can be useful for scientific research in the field of studying the nature and evolution of coronal holes and their connection with other structures on the Sun.
