Welcome on the Sloan Digital Sky Survey Mirror Site!
This is a service provided to the astronomical community by the DAME working group.

User-oriented navigation through the SDSS:
The mirror site, located at the italian GRID S.Co.P.E. Data Center, hosts and offers the complete Sky Survey Database, together with all tools and resources within the official SDSS website to generate scientific queries and to obtain data results. It provides also a subset of image archive, covering a wide portion of southern sky.
The following links are referred to specific topics on how to use the available resources:
A quick survey about data types and available resources click here;

Local SDSS image archive covering KIDS Survey area
A subset of the sky object image archive has been made available on the local mirror site, related to the sky coverage overlapping KIDS survey project area.
All the image files described below are named using the following rule:
http://dames.scope.unina.it/kids/fpC-[RUN(six_digits)]-[RERUN]-[BAND]-[CAMCOL]-[FIELD(four_digits)].fit.gz
for example: http://dames.scope.unina.it/kids/fpC-001231-40-g-1-0011.fit.gz
The following links are referred to all primary SDSS objects in the overlap area, organized by band:
The entire object list (all bands) is available at this link.
At this mirror site SQL Search page you can obtain objects (in terms of their ra, dec, run, rerun, camcol, field parameters), by typing a query like reported in the following SQL code example:
SELECT p.ra, p.dec, p.run, p.rerun, p.camcol, p.field from PhotoTag p WHERE p.ra BETWEEN [VALOREDIRAINDEG] AND [VALOREDIRAINDEG] AND p.dec BETWEEN [VALOREDIDECINDEG] AND [VALOREDIDECINDEG] AND p.mode = 1
Moreover, if you want to perform any dynamic cross identification of objects with a your own object list, at this mirror site CrossID SQL page you can obtain objects (in terms of their ra and dec parameters), by typing a query like reported in the following SQL code example:
SELECT p.ra, p.dec, p.run, p.rerun, p.camcol, p.field from PhotoTag p FROM #x x, #upload u, PhotoTag p WHERE u.up_id = x.up_id and x.objID=p.objID
DAME is a collaboration between INAF OACN, Dip. of Physics Science of University Federico II and Caltech Institute aimed at designing and developing instruments and tools for scientific data mining, based on information and comunication technology, funded by the Italian Ministry of Foreign Affairs as well as by the European project VOTECH (Virtual Observatory Technological Infrastructures) and by the Italian PON-S.Co.P.E.
