Table information for 'spectra_pn_archive.raw_data'

General

This table is not available for ADQL queries and through the TAP endpoint.

Resource Description:

Spectra of planetary nebulae obtained at the AZT-8 telescope (0.7-m, Fesenkov Astrophysical Institute, Kamenskoe Plato, Almaty, Kazakhstan) during 1970–1998. Observations were carried out with a diffraction spectrograph equipped with the UM-92 image tube, in the 4000–8000 Å range, recorded on A-600 and A-600U photographic plates.
