The Hubble Deep Field Data Products:
| Raw Data || Can be extracted from the
HST archive. |
| Version 1 || No longer available on line. We recommend using version 2. |
| Version 2 || Final reduced images and catalogs.|
The HDF data were released for general use on January 15, 1996. We
have tried to anticipate the needs and desires of most astronomers,
while keeping the data volume reasonable. The data products,
from least processed to most processed, are listed below.
The data volume, even for final images, is considerable. To reduce the
load on the STScI ftp site and speed data transfer in other parts of
the world, several sites have agreed to mirror the STScI data repository.
Check their web pages for details on how to transfer the data.
Other HDF data sites:
CADC (Canada); and
Available January 15, 1996.
This is essentially as received from the telescope, with all the cosmic
rays, hot pixels, and other defects. It will probably not be useful for most people.
This is best obtained on exabyte tape, as it consists of
roughly 3 Gbytes of data. Request a tape
by sending email to firstname.lastname@example.org. (The raw data can also be
extracted over the internet from the
HST archive, but this will be
prohibitively slow for the whole data set.)
Available January 15, 1996. As of November 1, 1996, these data are
no longer available on line. We recommend the use of version 2 data.
These data reflect processing up to January 15, 1996. A number
of shortcuts were taken to make these
data available within three weeks of the last observation.
Available February 29, 1996.
Essentially all of the data
have been used in the final stacks, and the images have been combined
with weights that are optimal for faint sources.
