Set of samples of astronomical data gathered by 7 different surveys: Calar Alto Legacy Integral Field Area Survey (CALIFA), Herschel Multi-tiered Extragalactic Survey (HerMES), Low Frequency ARray (LOFAR), Sloan Digital Sky Survey's Baryon Oscillation Spectroscopic Survey (SDSS_BOSS), Sloan Digital Sky Survey's Mapping Nearby Galaxies at Apache Point Observatory (SDSS_MaNGA), VIsible MultiObject Spectrograph (VIMOS) and Wide-Field Infrared Survey Explorer (WISE)

Universitat Autònoma de Barcelona. Group on Interactive Coding of Images (GICI). Description of methods used for collection-generation of data: Data obtained from observatory data archive website CALIFA: CALIFA DR3 data archive https://califa.caha.es/FTP-PUB/reduced/V500/reduced_v2.2/ - HerMES: Herschel data base in Marseille https://hedam.lam.fr/HerMES/download_files.html - LOFAR: LoTSS Data Release 2 (DR2) https://lofar-surveys.org/dr2_release.html - SDSS_BOSS: SDSS DR9 Science Archive Server (SAS) https://dr9.sdss.org/fields - SDSS_MaNGA: SDSS data access https://www.sdss4.org/dr17/manga/manga-data/data-access/ - VIMOS: ESO ESO Science Archive Facility (Raw Data) http://archive.eso.org/eso/eso_archive_main.html - WISE: NASA/IPAC infgrared science archive - WISE Image Service https://irsa.ipac.caltech.edu/applications/wise/?__action=layout.showDropDown&;. Methods for processing the data - Data was converted from FITS format to raw using python library astropy, separating the FITS multiple extension into different .raw files. Instrument- or software- specific information needed to interpret the data: imagej or fiji. Telescope diameters: CALIFA: Calar Alto 3.5 m telescope - HerMES: Far Infrared and Submilimetre Telescope (FIRST) 3.5 m - LOFAR: 70,000 LOFAR antennas spread across Europe, with the majority in the Netherlands. Antennas located in the Netherlands are combined and a virtual telescope is created with a collecting surface of about 120 kilometers in diameter. SDSS_BOSS: 2.5 m wide-angle optical telescope, SDSS_MaNGA: 2.5 m wide-angle optical telescope, VIMOS: Melipal (UT3) 8.2 m, WISE: 40 cm infrared telescope. Quality-assurance procedures performed on the data: Images pixel value differences are zero compared to original FITS, Images are checked for good S/N ratio and no lens, atmospehric or CCD distortions.
