charles 7 Tus and rising i think you may be incorrect.
Charles
you seem to be well educated in such matters...isnt a 90 degree hole at zero azimuth a vertical hole? hence would make jan correct.....
90 degree holes dont really have an azimuth or direction as they are going straight down (o degrees). If it were heading north towards all those barrumundie then compass would be set to 360 degrees mag north.
ho hum
as for width would be good to see all other holes otherwise who knows it could be a metre wide if it were running east west?? why not show all holes.
more info required IMO
