This atlas covers the southern hemisphere sky (declinations less than +15 degrees). The observations were taken with a robotic camera operating at Cerro Tololo Inter-American Observatory (CTIO) in Chile. obs_copyright = By courtesy of Swarthmore College Incorporated obs_copyright_url = http://amundsen.astro.swarthmore.edu/SHASSA/index.html obs_copyright_url = http://amundsen.astro.swarthmore.edu/SHASSA/ack.html client_category = Image/Gas-lines/Halpha client_sort_key = 06-02-01 hips_creation_date = 2010-12-13T12:00Z hips_release_date = 2019-05-05T07:18Z hips_builder = Aladin/HipsGen v10.123 hips_creator = CDS hips_version = 1.4 hips_order = 4 hips_frame = galactic hips_tile_width = 512 hips_tile_format = png jpeg fits dataproduct_type = image hips_pixel_cut = -10 20000 moc_access_url = http://alasky.u-strasbg.fr/SHASSA-H3/Moc.fits #hips_service_url = http://alasky.u-strasbg.fr/SHASSA-H3 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 = the Southern H-Alpha Sky Survey Atlas (SHASSA), which is supported by the National Science Foundation prov_progenitor = SHASSA bib_reference = 2001PASP..113.1326G bib_reference_url = http://simbad.u-strasbg.fr/simbad/sim-ref?bibcode=2001PASP..113.1326G&simbo=on #All observations used in the survey were obtained in the period 1997 November to 2000 October t_min = 50753 t_max = 51847 obs_regime = Optical # 656.3 nm em_min = 6.56e-7 em_max = 6.56e-7 hips_pixel_scale = 0.007157 moc_sky_fraction = 1 hips_estsize = 4504376 hips_order_min = 0 hips_pixel_bitpix = 32 hipsgen_date = 2019-05-05T07:18Z hipsgen_params = out=/asd-volumes/sc1-asd-volume10/SHASSA-v2/SHASSA-H3 UPDATE
