I don't understand Glasgow's school catchment tool thing, any help?

I am quite an intelligent person but this has defeated me. How do I know the catchments? We want to be in St Fillan's catchment in the south side.

Are you using the tool on the Glasgow City Council website? You can select eg Roman Catholic Primary School Catchments on that and then click and zoom in to view the streets it includes. This is St Fillans outlines in blue, but you can zoom in further to see the streets in more detail online, I just can't fit it onto my screen to take a photo!
