WebNov 13, 2014 · The frame classes that are built in to astropy are ICRS, FK5, FK4, FK4NoETerms, and Galactic. The string aliases are simply lower-case versions of the class name, and allow for creating a SkyCoord object and transforming frames without explicitly importing the frame classes. WebWe specify coordinates on the sky using astropy.coordinates.SkyCoord objects. This allows us a great deal of flexibility in how we specify sky coordinates. We can use different coordinate frames (e.g., Galactic, equatorial, ecliptic), different units (e.g., degrees, radians, hour angles), and either scalar or vector input. driving theory 4 all app WebNov 19, 2024 · from astropy import units as u from astropy.coordinates import SkyCoord c_gal = SkyCoord(l=0.0*u.degree, b=90.0*u.degree, frame='galactic') print(c_gal.fk5) … WebJan 8, 2024 · Using the SkyCoord High-Level Class. ¶.
