Downloads a list of objects defined by RA and DEC coordinates.

The ra, dec and save_path lists are mandatory and must have same length.

Parameters:

ra (List[float]) – The list of RA coordinates of the desired objects.
dec (List[float]) – The list of DEC coordinates of the desired objects.
save_path (List[Path], optional) – The list of path where files should be saved.
base_path (str, Path, optional) – The path that will be appended at beggining of every paths if save_path is None.

cutout(ra: float, dec: float, save_path: Path | None = None, base_path: str | Path = '', mag_r: float | None = None) → None[source]#

Downloads a single Legacy Survey object RGB stamp defined by RA and DEC.

Parameters:

ra (float) – Right ascension of the object.
dec (float) – Declination of the object.
save_path (pathlib.Path, optional) – Path where downloaded file will be stored.
base_path (str, pathlib.Path, optional) – The path that will be appended at beggining of every paths if save_path is None.
