J-NEP Public Data Release (PDR202107)
J-NEP Public Data Release (July 2024) (JNEP-PDR202107) is based on images observed with 60 optical bands collected by the JST250 telescope and the PathFinder instrument. This first public data release was publicly released on July 2024.
It includes two types of data: FITS images and single and dual catalogue data (parameters measured from images, such as photometry or morphology data). Single catalogues are the ones where the detection and photometry have been done on each image independently. Meanwhile, dual catalogues are the catalogues where the detection and photometry have been done using as reference image the r-SDSS image.
