Comment: added explicit dr2 to urls


The catalogs API can be used to do this same query with a single curl command.  Here is a sample command that cross-matches the PS1 DR2 catalog with a list of positions in the file sn2005.csv:

Code Block
titlecurl example
curl -F radius=0.000833 -F 'file=@sn2005.csv' \
	-X POST > sn2005.ps1.csv


Code Block
titlePython requests example
import requests
r = 0.000833			# radius in degrees
filename = 'sn2005.csv'
url = ''

r =, params=dict(radius=r), files=dict(file=open(filename,'rb')))
print(r.text, end='')	# print output without trailing newline
