Information on Service 'Flash/Heros Spectra Web Interface'

[Use this service from your browser]

Further access options are discussed below

Spectra from the Flash and Heros Echelle spectrographs developed at Landessternwarte Heidelberg and mounted at La Silla and various other observatories. The data mostly contains spectra of OB stars. Heros was the name of the instrument after Flash got a second channel in 1995.

Overview

You can access this service using:

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.

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 Common name of object observed. N/A meta.id;src
upload Upload Upload a list of target positions; this expects a text file with three floats per line (ICRS RA, Dec, radius, all in decimal degrees). N/A N/A

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.
