Information on resource 'Northern Sky Narrowband Survey: Continuum HIPS'

Services defined within this resource descriptor

• NSNS DR0.2: Estimated variance of visual continuum

  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.

• NSNS DR0.2: RGB continuum

  The Northern Sky Narrowband Survey maps the entire northern hemisphere down to a declination of -16° at an angular resolution of about 10 arcsec.

  Red, green and blue continuum with partially subtracted stars as compressed 8-bit color HIPS for easy visualization. See http://www.simg.de/nebulae3/dr0_2 for other data sets.

• NSNS DR0.2: Visual continuum

  The Northern Sky Narrowband Survey maps the entire northern hemisphere down to a declination of -16° at an angular resolution of about 10 arcsec.

  Star-subtracted visible continuum as a combination of the red, green, and blue color channel in Rayleighs per nm. H-alpha was subtracted, but the data still contains some emission from SII, OIII and H-beta. See http://www.simg.de/nebulae3/dr0_2 for other HIPS.

The Wisconsin H-alpha Mapper (WHAM) and its H-alpha Sky Survey have been funded primarily by the National Science Foundation. The facility was designed and built with the help of the University of Wisconsin Graduate School, Physical Sciences Lab, and Space Astronomy Lab. NOAO staff at Kitt Peak and Cerro Tololo provided on-site support for its remote operation.
