J-PAS Early Data Release (EDR)
J-PAS Early Data Release (November 2024) (J-PAS EDR) provides scientific data in 54 narrow-band filters, 2 intermediate-band filters and the iSDSS band covering an effective area of ~17 square degrees. J-PAS EDR is based on images collected from May 2023 to May 2024 by the JST250 telescope with the JPCam camera attached to it.
This early data release provides two types of data: images and catalogue data (parameters measured from coadded and individual reduced images, such as photometry or morphology data).
