Example use

The following code snippet downloads the Hi-GAL maps in a 15 arcminute radius around the IRDC G035.39-00.33:

import os
import astropy.units as u
import astropy.coordinates as c
from gethigal.requestform import RequestForm

home_dir = os.path.expanduser('~')

radius = 15*u.arcmin
skycoord_g035_39 = c.SkyCoord(284.2875*u.deg, 2.1294*u.deg, frame = 'fk5')

# Opens a Firefox session with "save file" pop-ups
getter = RequestForm(skycoord_g035_39, radius, submit = True)

# After the files are saved, moves them to a designated directory
getter.fix_download_loc(os.path.join(home_dir, 'Downloads/'), 'data/',
                        globber = "HIGAL*354*.fits", lay_low = True)

# Quits the browser session
getter.quit()
