Thanks,
Ben, that makes sense although I think the angles I have can be considered
the direction 'to' and I want direction 'from' so adding a negative makes
them come from the direction I need.
I should add I don't really know what flip does so will ignore that.
thanks for the responses.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
