6th Sun upper limb Hc 45° 56.5' S.D. 15.8' ref. 0.9' Hs 46° 13.2'
6th Sun center Hc 46° 9.8' ref. 0.9' Hs 46° 10.7'
Average fixed angle for 6th Sun is 46° 12'
9th Sun upper limb Hc 55° 58.2' S.D. 15.8' ref. 0.6' Hs 56° 14.6'
9th Sun center Hc 56° 20.5' ref. 0.5' Hs 56°21.0'
Average fixed angle for 9th Sun is 56° 18'
note- The calibrated fixed angle for each Sun is used as the Hs for lower limb, upper limb, and center observations. Try to use the same part of the Bris on all observations.
I hope that you plan to use a sextant (metal) as a standard and alternate observations with sextant and Bris at the beach for a better calibration.
