RELICS Observations

190-orbit Hubble Treasury Program (PI Coe)

  • GO 14096
  • Oct. 9, 2015 - April 2017 (click for full schedule)
  • 170 orbits for clusters + 20 orbits for supernova follow-up
    (8 non-disruptive targets of opportunity)
  • 46 fields lensed by 41 clusters: 5 orbits each
      – 3 orbits ACS (minus archival) in F435W, F606W, F814W
      – 2 orbits WFC3/IR in F105W, F125W, F140W, F160W
      – same 7 filters as the Frontier Fields (0.4 - 1.7 microns)
  • 19 parallel blank fields: 3 orbits each with WFC3/IR + UVIS F350LP
  • 2 epochs separated by 25 - 60 days enabling a supernova search

100-hour Spitzer GO Program
(PI Bradač)

  • GO 12005
  • Dec. 2015 –
  • 1.2 hour per band in each of IRAC ch1 (3.2-3.9 microns) and ch2 (4.0-5.0 microns)
  • minus archival time in 34 clusters (other 7 already observed to these depths)
