HI Tarquin and Andrew,

Many thanks for that, We were just lost, I think we'll be able to pick it up from here with your helpful guidance. Should just be a case of looking through the .th files and looking for all the 90's

I hope you are both well.

Al.

As a point to note -90 and Down at treated differently for clino
correction, they can be treated ed the same

 From the survex manual

     "*infer plumbs on" tells cavern to interpret gradients of +/- 90
degrees as UP/DOWN (so it will not apply the clino correction to them).
This is useful when the data has not been converted to have UP and DOWN
