The Brightest of Reionizing Galaxies (BoRG) observations were first
obtained in HST Cycle 17 in program GO 11700 (PI: Michele Trenti)
and continued in Cycle 19 with
program GO 12572 (PI: Michele Trenti).
BoRG is an ongoing pure-parallel program that obtains WFC3 imaging in
four filters (F606W, F098M, F125W, F160W) on random sightlines at high
Galactic latitudes (|b| > 30 degrees). BoRG also assimilates data
from the similar Hubble Infrared Pure Parallel Imaging Extragalactic
Survey (HIPPIES) pure-parallel program (GO 11702; PI: Yan)
as well as the
coordinated parallel observations acquired as part of the Cosmic
Origins Spectrograph (COS) GTO program (GO
12025). The filter selection
of the HIPPIES program and the earlier part of the COS GTO program
differ from BoRG in that those datasets used the F600LP filter instead
The data are available through the browser.
