Service Documentation

This is VO-compatible archive of spectra exposed by the team of Stellar department of Astronomical Institute of the Czech Academy of Science in their allocated time on spectrograph HEROS attached to the Ondrejov 2m Telescope from October 2000 to March 2003. The spectra were exposed by two cameras - red (5840-8350A) and blue (3650-5650A). The HEROS was at that time on the loan from Landessternwarte Heidelberg.

Overview

You can access this service using:

This service is published as follows:

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD
mime Type MIME type of the file served N/A N/A
ssa_dateObs Date Obs. Midpoint of exposure d time.epoch
ssa_location Location ICRS location of aperture center deg pos.eq
ssa_targname Object Somewhat cleaned name of the target object as given in the file. The names should either be SIMBAD-resolvable or give a reference for the source. Some names we could not make sense of are marked with a tilda (~); any help figuring out what they are is appreciated. N/A meta.id;src

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
