Abstract:
The Cluster Lensing And Supernovae survey with Hubble (CLASH) is a
Hubble Space Telescope (HST) Multi-Cycle Treasury programme
that observes 25 massive galaxy clusters, 20 of which were
X-ray-selected to preferably choose dynamically relaxed clusters, and
5 additional "high magnification" clusters, which were selected
based on their optical lensing properties. CLASH aims to study the
dark matter distribution of the clusters and find magnified
high-redshift galaxies behind them. CLASH observations were carried
out in 16 bands from UV to NIR to derive accurate and reliable
estimates of photometric redshifts.
We present the CLASH photometric redshifts using 16 HST bands and
study the photometric redshift accuracy including a detailed
comparison between photometric and spectroscopic redshifts for the
strong lensing arcs using the measurements from the cluster
MACSJ1206.2-0847.
Description:
Photometric + photo-z (BPZ) catalog (produced 2011-10-25) for macs1206
(processed 2011-08-15).
Note: photo-z estimates are intended for galaxies only.
Stars may be identified as having higher values of SExtracor stellarity.
Based on 0.065"/pix images produced by AMK's MosaicDrizzle.
Objects detected in a weighted sum of ACS+IR images.
Pruned by selecting flag5sig=0 (gets rid of cosmic rays and <5-sigma
detections).
Position, aperture, and shape measurements determined in the detection image
Photometry measured in isophotal apertures
For each filter, we provide:
- magnitude & uncertainty
- flux & uncertainty
- detection significance
Both fluxes and magnitudes have been corrected for:
- galactic extinction: E(B-V)=0.06283
mag, magerr = 99, 1-sigma limit: non-detection (flux<0)
mag, magerr = -99, 0: unobserved (outside FOV, in chip gap, etc.)
This catalog was created by the CLASH Image Pipeline
