Issues
The FITS RA and DEC header cards contain positions obtained from the
telescope guidance system. These positions are frequently off by several
arcminutes with respect to the actual object. Therefore, in the metadata
table, the positions used for SSA location are obtained from SIMBAD
whenever the target names could be resolved.
The nomenclature of objects in the FITS header is somewhat eclectic. For the
SSA target name, we use translated names that can be resolved using SIMBAD.
However, there are quite a few names we could no longer make sense of;
we marked these in the SSA target names with a tilda (~). For
these spectra, the SSA location is constructed from the (flaky) positions
in the RA, DEC header cards. Any assistance in figuring
out proper designations for the objects observed is appreciated.
This service currently only serves data from the commissioning phase
and from guaranteed time on the instrument. Spectra taken
in visitor mode may be available from ESO in unreduced form.
If you have reduced spectra obtained with FEROS and would like to publish
them, please do not hesitate to contact gavo@ari.uni-heidelberg.de.
Overview
You can access this service using:
-
dlget --
a datalink interface letting specialized clients retrieve parts of datasets or discover related data. You use this kind of service exclusively in combination with a pubdid, usually via a direct link.
-
dlmeta --
a datalink interface for discovering access options (processed data, related datasets...) for a dataset. You usually need a publisherDID to use this kind of service. For special applications, the base URL of this service might still come handy: http://dc.zah.uni-heidelberg.de/feros/q/sdl/dlmeta
This service is not published.
This can mean that it was deemed too unimportant, for internal
use only, or is just a helper for a published service.
Equally likely, however,
it is under development, abandoned in development or otherwise
unfinished. Exercise caution.
