The survey covers about 98% of the southern sky (DR1) so it might be a good solution to use them as reference images. Need to check limiting magnitude for DR1-DR2.
Some of out telescope are deeper than the survey so be careful.

2 steps procedure:
It will list all the images overlapping the sky area defined by POS and SIZE (in degrees) in a csv file.
-
Loop over the url provided in the csv file (get_image column) to download each image.
-
Stack the images, as no stacked images seem to be provided and make a mosaic.
Limitation:
- apparently RA dec size is limited between 0 and 0.17deg (ERROR: Right ascension component of SIZE (0.5 deg) must be between 0.0 and 0.17 deg)
- apparently no stack image is provided, so will need to stack the data ourself. To be checked
