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.</description><referenceURL>https://dachs.fai.kz/spectra_pn_archive/q/web/info</referenceURL><type>Archive</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://fai.kz/__system__/obscore/obscore">FAI archives Obscore</relatedResource></relationship></content><capability standardID="ivo://ivoa.net/std/SODA#sync-1.0"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="base">https://dachs.fai.kz/spectra_pn_archive/q/sdl/dlget</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/DataLink#links-1.1"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="base">https://dachs.fai.kz/spectra_pn_archive/q/sdl/dlmeta</accessURL><queryType>GET</queryType><resultType>application/x-votable+xml;content=datalink</resultType><param std="true"><name>ID</name><description>The publisher DID of the dataset of interest</description><ucd>meta.id;meta.main</ucd><dataType arraysize="*" xsi:type="vs:SimpleDataType">char</dataType></param><param std="true"><name>responseformat</name><description>File format requested for output.</description><ucd>meta.code.mime</ucd><dataType arraysize="*" xsi:type="vs:SimpleDataType">char</dataType></param><param std="true"><name>maxrec</name><description>Maximum number of records returned.
