This workflow analyses a given astrophysics text (e.g. Astronomer's Telegram https://astronomerstelegram.org/). It extracts positions of mentioned astronomical sources and provides possible optical counter-parts with photometric data. The corresponding photometric data can be further used to estimate the redshit of the optical sources, that is a measure of the distance between the Earth and the optical source. Given the fact that the the tool that estimates the photometric redshift is still in staging mode on a local instance, due to non-standard package channels, the entire workflow can be found on the local galaxy instance: https://galaxy.odahub.fr/u/andreiv/w/atel-follow-up-photometric-data-legacy-survey-photoz The workflow withtout the last tool can be found on the usegalaxy.eu instance: https://usegalaxy.eu/u/avariu/w/atel-follow-up-photometric-data-legacy-survey
