Information on Service 'NSNS DR0.2: Estimated variance of visual continuum'
Further access options are discussed below
The Northern Sky Narrowband Survey maps the entire northern
hemisphere down to a declination of -16° at an angular resolution of
about 10 arcsec.
Estimated variance (square noise) of visual continuum (HiPS
simg.de/P/NSNS/DR0_2/vc) normalized to 30" pixels. Use these data to
assess the accuracy of the star and H-alpha subtracted continuum,
which is mainly determined by photon noise, whether from the signal of
interest or from contamination.
