      Description

      I am wondering if it would be straightforward to provide a "footprint" outline of the Stripe 82 area on the sky for use in highly zoomed-out context images in PDAC.

      If this is an easy task, in what format would we need to specify the coordinates of the online?

      I think we can do a calculation of four corners of all the coadded images and produce a sd9 region file for the outline.

      ==============================================

      How to generate the region files attached here:

      1)Get four corners data for all the coadds FOVs for SDSS:
      curl -o sdssFourCorners.json -d 'query=SELECT+corner1Ra,corner1Decl,corner2Ra,corner2Decl,corner3Ra,corner3Decl,corner4Ra,corner4Decl+FROM+sdss_stripe82_00.DeepCoadd;' http://lsst-qserv-dax01.ncsa.illinois.edu:5000/db/v0/tap/sync
      2)Convert the json file to csv using a tool on line:
      http://www.convertcsv.com/json-to-csv.htm
      3)Sort the csv file by corner1Ra
      4)Remove "^M"
      5)Convert the csv file to a region file by adding "polygon(" and ") #color=green" and a header "fk5"
      6)For only plot 1% or 10% FOVs:
      awk 'NR == 1 || NR % 100 == 0' input.reg > output_1pct.reg
      awk 'NR == 1 || NR % 10 == 0' input.reg > output_10pct.reg

      The region file can be loaded to Firefly.
