For a list of all services and tables belonging to this service's resource, see Information on resource 'CCD700 Ondrejov Spectra'
The CCD700 archive contains spectra exposed with 700mm camera of coude spectrograph at Ondrejov observatory 2m Perek telescope, Czech Republic. The spectrograph works in first and second order and typical spectral resolving power is 13000 in first order around Halpha region and twice in Hbeta. The propriatory period is set to one year after the exposure with possible exceptions. All spectra were taken by the team of Stellar department of the Astronomical Institute of the Czech Academy of Sciences, Astronomical Institute of the Faculty of Math anf Physics of Charles University, Prague, and Department of Theoretical Physics and Astrophysics of the Faculty of Science, Masaryk University, Brno. All spectra were reduced in IRAF by M. Slechta. VO technical help by Jiri Nadvornik.

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:
The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):
Name | Table Head | Description | Unit | UCD |
---|---|---|---|---|
mime | Type | MIME type of the file served | N/A | N/A |
obj_name | Object standard name | 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 | N/A |
ssa_dateObs | Date Obs. | Midpoint of exposure | d | time.epoch |
ssa_location | Location | ICRS location of aperture center | deg | pos.eq |
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.

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.
