Scientific paper

Using the T250 telescope of the Observatorio Astrofísico de Javalambre (OAJ) a survey of 8000 square degrees (JPAS) is going to be carried out in a system of 42 filters of ˜ 100-120Å (from 4000 to 8000Å). The T250 camera (JPCam) will have a mosaic of14 large format CCDs of ˜ 10k x 10k pixels. The T80 during the first two years of operation will be devoted to the calibration of the JPAS survey. This calibrationsurvey will be performed using a system of 14 filters and a camera equipped with a CCD similar to the ones in JPCam.The JPAS and T80 surveys will produce respectively ˜ 770 TB and ˜ 43 TB of raw data. This poster describes the maincharacteristics of the storage and computation hardware needed to the archiving and processing of the OAJ data. The data management software will automatically proceed with storage and reduction of the data collected each night of observation by the OAJ telescopes (˜ 1.5 PB). It will correct the instrumental imprint on the data, validate the images, and update the databases to calculate the telescope targets for the following nights. When the survey fields is being completed the software will produce the average mosaic of the sky area and extract the source catalogs.
