Morning All,
Before I hit the sack after a verrrry long 12 hr night shift I managed
to
use my tired old eyes to get another 2 sets of readings. Here are the 5
sets I have so far.
Details are 200mm diameter blank
197mm optical diameter
Moving source tester
2005 ROC
Zones calculated using front six and Carlins method. These are
the main
zones. In the next coupla days I'll use the intermediate option and a
similiar #of readings from them. Unfortunately night shift will intervene
for the next few days.
