From IRAF to Python: new software architecture for echelle spectroscopy at Universidad Tecnologica de Pereira Observatory

With the evolution of technologies and the discontinuation of IRAF support for, Universidad Tecnológica de Pereira Observatory (OAUTP) identified the need to migrate to a new tool that would not only replace Image Reduction and Analysis Facility (IRAF) but also significantly enhance the Echelle spectra reduction process. To address this need, wecreated and implemented a new software architecture in Python, utilizing Astropy and PyReduce libraries to improve the processing of Echelle spectra at the UTP Observatory. Our methodology was structured into five steps: (1) requirements analysis, (2) solution design, (3) software development, (4) quality testing, and (5) system deployment. We analyzed data from stars HD108, HD12560, and HD194649 using a ThAr lamp to detect and create 2D spectra.The findings indicate that the new architecture effectively identifies orders and generates 2D spectra, establishing a formal foundation for software development at the UTP Observatory. This represents a significant advancement in astronomical spectroscopy, offering an improved alternative for processing Echelle spectra in astronomical telescopes.
