obs_collection = Northern Sky Narrowband Survey
obs_description = Estimated variance (square noise) of H-alpha (HiPS simg.de/P/NSNS/DR0_2/halpha) normalized to 30" pixels. Use these data to assess the accuracy of the continuum-subtracted H-alpha, which is mainly determined by photon noise, whether from the signal of interest or from contamination.
prov_progenitor = Calculated from 5" intermediate data of the Northern Sky Narrowband Survey DR0.2, see http://www.simg.de/nebulae3/dr0_2
