numina offers the interface for executing data reduction pipelines for various instruments of the Gran Telescopio Canarias (GTC), in particular EMIR, MEGARA and FRIDA. Additionally, numina includes code for performing common operations involved in astronomical image reduction workflows, allowing such functionality to be reused across pipelines for different instruments.

megaradrp reduces data for MEGARA, the optical Integral-Field Unit and Multi-Object Spectrograph designed for the 10.4m Gran telescopio Canarias (GTC) in La Palma, Spain. The online version of megaradrp allows for on-the-fly data processing, which includes bias correction, trimming, fiber tracing and fixed-aperture extraction, fiber-flat and twilight-flat correction and wavelength calibration. The offline processing version additionally includes a detailed cross-talk-corrected extraction and absolute flux calibration whenever possible.

Photutils provides tools for detecting and performing photometry of astronomical sources. It can estimate the background and background rms in astronomical images, detect sources in astronomical images, estimate morphological parameters of those sources (e.g., centroid and shape parameters), and perform aperture and PSF photometry. Written in Python, it is an affiliated package of Astropy (ascl:1304.002).
