Workflow associated with the PELE code. The input information is a list of galaxies with ID, RA, Dec, and size of the images, followed by the creation of masks, in which the user can check the objects to be masked and labeled as stars and main galaxy. Then the code automatically performs the image processing, including PSF homogenization, Butterworth filtering, binning functions, and the three-filter method. Prior to generating the final emission-line map, sigma clipping is applied to remove outliers that are overestimated, as discussed in Sect. 3.2.
