A COMPARATIVE ANALYSIS OF DECH AND IRAF SOFTWARE PACKAGES FOR THE PROCESSING OF ECHELLE SPECTRA

Abstract

A comparative analysis has been conducted on the application of DECH and IRAF software packages in the processing of echelle spectra obtained with the 2-meter telescope at the Shamakhy Astrophysical Observatory of the Ministry of Science and Education of the Republic of Azerbaijan. The advantages and limitations of both software packages have been presented. The study reveals that the DECH package stands out in terms of visual clarity and simplicity, offering an intuitive and user-friendly interface that facilitates ease of use. In contrast, the IRAF package excels in automation capabilities and time efficiency. However, due to its technical complexity, IRAF poses a steeper learning curve, particularly for novice users. In terms of measurement accuracy, it has been determined that both software packages are suitable for use and provide sufficiently precise results.
