- geturl(ra, dec, size=240, output_size=None, filters='grizy', format='jpg', color=False, type='stack')[source]
Get the URL for images in the table.
- Parameters:
ra (float) – Right ascension of position, in degrees.
dec (float) – Declination of position, in degrees.
size (int) – The extracted image size in pixels (0.25 arcsec/pixel)
output_size (int) – output (display) image size in pixels (default = size). The output_size has no effect for fits format images.
filters (str) – The string with filters to include.
format (str) – The data format (options are "jpg", "png” or "fits").
color (bool, optional) – If True, creates a color image (only for jpg or png format). If False, return a list of URLs for single-filter grayscale images.
- Returns:
The url for the image to download.

str
- get_ps1_pic(path, objid, ra, dec, size, band, safe=False, save=False)[source]
Downloads PS1 picture (in fits) centered at a given location.
- Parameters:
path (str) – The filepath where the fits file will be saved.
objid (int) – The PS1 objid of the object of interest (to save as filename).
ra (float) – Right ascension of position, in degrees.
dec (float) – Declination of position, in degrees.
size (int) – The extracted image size in pixels (0.25 arcsec/pixel)
band (str) – The PS1 band.
safe (bool, optional) – If True, include the objid of the object of interest in the filename (useful when saving multiple files at comparable positions).

path (str) – The directory to search.
- Returns:
The list of absolute paths to all files called 'name' in 'path'.
- Return type:
list
