The publication software DaCHS comes with a preconfigured authority
x-unregistred. Before version 2.3, it would let records with this null
authority into the VO. This authority's exclusive purpose is to let us
delete any such records.
This table holds metadata for the “Patrol” and “Meteor” plates from
DASCH, i.e., very wide-field observations presumably not useful in
global discovery. These data products are therefore not re-published
through obscore. For the “narrow” plates, see the narrow_plates table.
This table holds metadata for the parts of DASCH counting as targeted
observations (plate scale below 400 arcsec/mm. “Patrol” and “Meteor”
plates in DASCH nomenclature are found in the wide_plates table.
Data Discovery Using the Virtual Observatory Registry

Description:
There are many ways to access registry data. A fairly powerful one is
the Web Interface to the Relational Registry (WIRR for short) at
http://dc.g-vo.org/WIRR To actually speak to the VO services
discovered, clients speaking the service's protocols are still
required. In this tutorial, Topcat plays that role. Starting from a
simple use case, we work up to investigating the Tully-Fisher relation
in different bands using independently discovered resources.
This is a deep optical mosaic of the Fornax cluster’s core, covering
1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI,
using a transparent filter that nearly equals the no-filter throughput
and thus provides a high signal-to-noise ratio. Based on an
approximate conversion to V-band magnitudes, the unbinned and binned
mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and
27.8 mag/sq.arcsec, respectively.
