All data obtained with the Perek 2-m telescope spectrographs are automatically archived, and after the expiration of the proprietary period they are available to the broader community at the Czech Virtual Observatory (CZVO). Two sets of archives are presently available: spectra obtained with Reticon and HEROS. The HEROS archive is also avealable at the CZVO including in addition the spectra obtained with single order spectrograph (CCD700).
Rules for usage of the archival data
All observed data are the property of Astronomical Institute of the Czech Acaemy of Science and are included in the data archive facilities of the Perek 2-m telescope. Browsing the archive require authentication. The use of new and archival data must be cited in the publications that are based on them.
The proposers of the approved observing nights on Perek 2-m Teleskope have exclusive access to their scientific data for the duration of a proprietary period, normally of one year, after which the data becomes available to the community at large. The proprietary period usually lasts one year from the acquisition of the exposure. The proposers of the approved observing nights may shorten this period. Conversely, in justified cases approved by the head of the department, the proprietary period may be extended.
Calibration exposures are immediately available for general use. Information on exposures of observed objects is also published. The expositions of the objects can be used immediately for the technical needs of maintenance and development of the telescope.
After the expiry of the proprietary period, all observations are freely available to the community at large for scientific purposes or for teaching, dissemination and promotion.
