ESO TAP_OBS: a TAP service to browse and access raw and reduced data, and to query the ambient measurements, of the La Silla Paranal Observatory.

Description:
TAP_OBS is the ESO Science Archive TAP endpoint for observations (raw and reduced data) and ambient measurements (atmospheric seeing, turbulence, water vapour, relative humidity, air pressure, etc.) taken at the La Silla Paranal Observatory, including the Chajnantor (APEX) data.
The Table Access Protocol (TAP) lets you execute queries against our database tables, and inspect various metadata. Table Upload is not currently supported, though it is foreseen for a next release.
The IVOA ObsCore standard service is also provided (table name: ivoa.ObsCore), but currently only for reduced data.
Other tables exposed are the dbo.raw describing all the LPO observations, the ambient tables (in the asm schema), plus the provenance table to close the loop between the raw and the reduced data, but also to describe the relationships between reduced data (e.g. a source table originating from a reduced image, etc.).
A sibling service (TAP_CAT, endpoint: https://archive.eso.org/tap_cat) exists and can be used to query the astronomical catalogs produced by the principal investigators of ESO programmes (ESO public surveys included).
Estimated distances to 1.33 billion stars in Gaia DR2

Description:
This catalogue provides distances estimates (and uncertainties therein)
for 1.33 billion stars over the whole sky brighter than about G=20.7.
These have been estimated using the parallaxes (and their uncertainties)
from Gaia DR2. A Bayesian procedure was used involving a prior
with a single parameter L(l,b), which varies smoothly with Galactic
longitude and latitude according to a Galaxy model. The posterior is
summarized with a point estimate (usually the mode) and a confidence
interval (usually the 68% highest density interval). The estimation
procedure is described in detail in the `accompanying paper`_,
which also analyses the catalogue content.

Science images from the HST and HLA collections hosted at ESAC/ESA. All public HST observations in calibrated and science-ready form are synchronised with the MAST services for HST reprocessed public data and corresponding metadata. The European HST archive interface can be accessed at https://hst.esac.esa.int/ehst
This service delivers (most of) the datasets held at
EVN Data Archive. In addition to the default (nonstandard)
way of just appending accrefs to the get access URL, there is also a
very simple datalink service here that, for each dataset, essentially
just gives the dataset itself and possibly a preview. More advanced
datalink services might be available.
Some datasets may be embargoed, in which case the access yields a 403.
Credentials for individual files may be obtained by contacting the
site operators.
The EVN Data Archive's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: main from the evn schema, obscore from the ivoa schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.
