Hello, I hope you are all doing well. I have a few questions concerning the measurements selection, and I am interested only on the anchoring mesh measurements. In fact, for optimisation issues, I would like to be able to select only measurements of interest: For example, I want to get the results coming from sources: X and Y, and targeting the anchor 6771. Now I can get the measures targeting the anchor 6771 using this code from Altas Cousteau ################################################################## from ripe.atlas.cousteau import MeasurementRequest filters = {'tags': ['anchoring','mesh',6771] } measurements = MeasurementRequest(**filters) #################################################################### But I have no idea of how to make a filter on the sources as well, since all we can access through the measurements are the number of anchors requested and not their ids. Do you know a way to get access to the sources of a measurement via Atlas Cousteau or another Ripe Tool ? Thank you -- Sanaa
