WebLocation (obs): use a string name of the observatory (e.g., 'palomar') or give the earth location as an astropy EarthLocation object, or as a tuple of three numbers: (longitude, latitude, altitude). The numbers can be given as astropy Quantity objects, or as numbers, in which case they are assumed to be in degrees and meters, respectively. WebMar 15, 2016 · Astropy can answer that. In the example below, we make a SkyCoord to look up the coordinates of M33 online, and then transform to horizontal coordinates ( AltAz) using an astropy.time.Time object for when we’re observing and an EarthLocation object for the park: >>>. >>> import numpy as np >>> from astropy import units as u >>> from …

WebNov 5, 2024 · I like the idea for EarthLocation for CIRS, TETE, and AltAz, as well as a possible get_cirs_posvel() extension. Also agree that it would be super useful to think a bit more about observer locations away from Earth, in Earth orbit, at the Earth-Sun Lagrange points, etc. For those having an actual coordinate may end up easiest , i.e., to adapt ... WebAug 12, 2024 · Any suggestions or alternatives would be appreciated. I think it is not really an API, it is more like a database (although it can have an API). Celestia, Google Sky Map, both have this DB. Celestia is opensource, and its database is free. JPL HORIZONS will do this and is callable from Python docs. burnet scott and white
