BOUNDARY FILES
Sky Atlas 2000: Boundaries for the 26 charts in the Sky Atlas 2000.0.
Uranometria 2000: Boundaries for the 473 charts in Uranometria 2000.0 atlas.
Atlas Coeli equinox 1950.0: Boundaries for the 16 charts making up Atlas Coeli by Becvar.
Atlas Borealis, Eclipticalis and Australis equinox 1950: Boundaries for the 80 charts making up Atlas Borealis (+30 degrees to +90 degrees), Eclipticalis (-30 degrees to +30 degrees) and Australis (-90 degrees to -30 degrees) by Becvar.
AAVSO 1980 Variable Star Atlas: Boundaries for each of the 178 charts found in the American Association of Variable Star Observers (AAVSO) Variable Star Atlas, 1980 Edition.
MicroSky (Palomar Sky Survey I) Fields: MicroSky field identifications for each of the Palomar Sky Survey's 6.4-degree-square charts. Boundaries include the -30 degrees dec zone, which was not initially part of the Palomar Sky Survey.
Palomar Sky Survey (+ MCG, CGCG) Field Bounds: The approximate field boundaries for each of the Palomar Sky Survey's 6.4-degree-square charts. Boundaries include the -30 degrees declination zone, which was not initially part of the Palomar Sky Survey, but was later released with it. Boundaries also include the Whiteoak extension to the survey done in the 1950s.
Second Palomar Sky Survey Field Boundaries: Approximate boundaries for each field in the second Palomar Sky Survey from the north celestial pole to the celestial equator.
Constellation Figures and IAU Equinox 1875 Boundaries.
Official IAU Equinox 1875 Constellation Boundaries.
Constellation Positions: Sets your field position to approximate center of selected constellation and automatically adjusts the HyperSky field scale for best overall view of it except huge constellations like Hydra where two or three postions are given.
ESO/SERC Southern Survey Field Boundaries: This is the southern sky complement of the first and second Palomar sky surveys and includes ``south equatorial extension'' covering the northernmost declination zones (-15 degrees, -10 degrees, -5 degrees, 0 degrees) and therefore overlaps the POSS in these areas.
Hubble Guide Star Catalog Region Boundaries: 9,537 small region boundaries and the 732 less commonly used large region boundaries. Position-list GLS.LS contains the equinox 2000 positions of the field centers of all 9537 small regions in the Hubble Space Telescope (HST) Guide Star Catalog (GSC).
