# Stars from the GTSh10 catalogue in "Shajn's plan"

## TL;DR

This paper analyzes stars from the GTSh10 catalogue within the framework of Shajn's Plan to enhance the database of red dwarf observations, utilizing Virtual Observatory tools for data refinement and cross-identification.

## Contribution

It introduces a method for cross-identifying GTSh10 stars with Shajn's Plan data and demonstrates the use of Virtual Observatory tools for data analysis and refinement.

## Key findings

- Successful cross-identification of GTSh10 and Shajn's Plan data
- Enhanced photometric and spectral data for red dwarfs
- Demonstrated Virtual Observatory applications for historical data analysis

## Abstract

We examined objects from the GTSh10 catalogue among the studied stars as a part of implementing the "Plan of Academician G.A. Shajn" (hereinafter - "Shajn's Plan") in order to replenish the database of photometric and spectral observations of red dwarfs. We consider the question concerning the cross-identification of data from the GTSh10 interactive version and the "Shajn's Plan "catalogs, as well as the access to the archive of photographic observations. The article is illustrated with examples of working with the obtained list by means of the Virtual Observatory in order to analyze the state of objects and/or to refine their photometric and spectral characteristics in the middle of the past century.
