(Top) Distribution of SuperBoRG fields (red circles) in ecliptic coordinates, overlaid on a temperature map from the WMAP 5-year data (Hinshaw et al. 2009). Most of the fields were selected from high Galactic latitudes (|b| > 30 deg), to avoid fields with significant Galactic extinction and/or dominated by foreground stars. (Bottom Left): Effective area and 5-sigma limiting magnitude of various extragalactic survey programs of HST. Survey programs included in SuperBoRG (red square) are shown with cross symbols; BoRG Cycles 17, 19, 22, 25 (orange), HIPPIES Cycles 17, 18 (blue), CLASH, RELICS, and COS-GTO (green). Legacy surveys such as CANDELS, including its extended version presented in Bouwens et al. (2019, CANDELS-B19), and HUDF09, HUDF12, and XDF programs are shown with gray squares. (Bottom Right): Histogram of limiting magnitude of the SuperBoRG fields. Survey programs are distinguished by the same color scheme as in the left panel.

Overview

SuperBoRG is an archival project that primarily aims to search for luminous galaxies and quasars at redshifts z > 7. SuperBoRG compiled HST’s multi-band imaging data previously taken in parallel observations designed for extragalactic science and reduced all data in a consistent manner. From both pure-parallel and coordinated-parallels programs with WFC3 in the past decade, it collected 316 independent sightlines with multi-band imaging data at moderate depth. The total area reaches ~0.41 deg^2, making it one of the largest area, extragalactic datasets. All data were reduced with a new pipeline with a few updates from the previous BoRG HLSP data release, including sophisticated sky subtraction and PSF matching. This data release includes imaging data and catalogs.

Data Products

The image products have the following file naming convention:

hlsp_superborg_hst_<ins>_borg-<id>_<filter>_v1_<ext>

where:

  • <ins> = Name of instrument, either "wfc3", "acs", or both ("acs-wfc3").
  • <id> = Target ID of the galaxy, e.g., "0006+1607".
  • <filter> = Name of filter used, e.g., "f600lp", or set to "det" for the detection image and "opt" for the optical-combined image.
  • <ext> = Type of image product, described below.

The catalog products have the following naming convention:

hlsp_superborg_hst_acs-wfc3_all_multi_v1_<ext>

where

  • <ext> = Type of catalog product, described below.

Note on "detection" and "optical-combined" files.

The "detection" image products make use of the F140W+F160W filters if F140W is available, F160W only if not.  They use "det" in the filter part of the file name.

The "optical-combined" image products make use of all of the following filters, depending on which are available: 'F300X', 'F350LP', 'F435W', 'F475W', 'F475W', 'F475X', 'F555W', 'F600LP', 'F606W', 'F625W', 'F775W', 'F814W', 'F850LP'.  They use "opt" in the filter part of the file name.

Note on segmentation map headers.

The headers of the segmentation map come from one of the HST images that went into making them, but they are effectively meaningless and should be ignored.  The segmentation map files are applicable to the detection images, and thus the individual keywords in the headers of these files should be ignored.

Data file types:

Images
_drz-sci.fits Science image at original resolution. Pixel scale is set to 0.08 arcsec.
_drz-wht.fits Weight map.
_drz-rms.fits Root-mean-square map.
_seg.fits Segmentation map, especailly useful for those using the source catalog.
_drz-conv-sci.fits Science image convolved to F160W PSF size.
Catalogs
_master.fits Master catalog for all sources in SuperBoRG.
_photometry.fits Source photometric flux catalog.
_redshift.fits Source redshift catalog.
_highz.fits High-redshift source flag catalog. If a source satisfies a color selection, the value for the corresponding column is set to 1; if not, 0. If the source is not qualified for the color selection, the value is set to -99.

 

Data Access

Bundles of all image products for a given target are available in the table below in .tar.gz file format (each is a few hundred MB in size).  The catalog files are provided in FITS format, and range in size from ~50 to ~200 MB.
