The instrumentation used is the Virginia Tech Spectral Line Imaging Camera (SLIC), specially designed for obtaining sensitive, arcminute-resolution, 10-degree wide images of the 6563 H-alpha recombination line of hydrogen, and the [SII]6717,6731 angstrom doublet emission of singly ionized sulfur. This survey cover the northern hemisphere (declinations greater than -15 degrees). obs_copyright = (c) Virginia Tech Physics - HEALPixed by CDS obs_copyright_url = http://www.phys.vt.edu/~halpha/ client_category = Image/Gas-lines/Halpha/VTSS client_sort_key = 06-03-01 hips_creation_date = 2013-09-16T10:05Z hips_release_date = 2019-06-18T13:19Z hips_builder = Aladin/HipsGen v10.130 hips_creator = CDS hips_version = 1.4 hips_order = 3 hips_frame = galactic hips_tile_width = 512 hips_tile_format = png jpeg fits hips_pixel_cut = -31 569 dataproduct_type = image moc_access_url = http://alasky.u-strasbg.fr/VTSS/Ha/Moc.fits #hips_service_url = http://alasky.u-strasbg.fr/VTSS/Ha hips_status = public master clonableOnce #For compatibility hips_initial_fov = 1.0921117184376416E-7 hips_initial_ra = 45.0 hips_initial_dec = 7.114779961355992E-8 hips_copyright = CNRS/Unistra obs_ack = http://www1.phys.vt.edu/~halpha/ack.html prov_progenitor = Virginia Tech Physics bib_reference = 1998PASA...15..147D bib_reference_url = https://ui.adsabs.harvard.edu/?#abs/1998PASA...15..147D #t_min = Start time in MJD ( =(Unixtime/86400)+40587 or https://heasarc.gsfc.nasa.gov/cgi-bin/Tools/xTime/xTime.pl) #t_max = Stop time in MJD obs_regime = Optical # 6563A H-alpha recombination line of hydrogen, and the [SII]6717,6731A doublet emission of singly ionized sulfur. em_min = 6.563e-7 em_max = 6.731e-7 hips_pixel_scale = 0.01431 moc_sky_fraction = 0.32813 hips_estsize = 1149036 hips_order_min = 0 hips_pixel_bitpix = -32 hipsgen_date = 2019-05-05T07:42Z hipsgen_params = out=/asd-volumes/sc1-asd-volume10/VTSS/Ha UPDATE hipsgen_date_1 = 2019-06-18T13:19Z hipsgen_params_1 = out=/asd-volumes/sc1-asd-volume10/VTSS/Ha UPDATE
