Antoine,
A Palm Pilot smart phone returned the following results (rounded to nearest minute):
UT 03:50:49 5/13/2016
aLat 47° 00' N aLon 122° 32' W° (Flt. Track Data)
GHA 238° 37'
LHA 116° 5'
Dec 18° 28' N
S.D. 16'
Hs 0° Upper Limb Sun
Hc 356° 59' (- 3° 1' )
Ho (-3° 1' )
Int 0°
Az 301.5°
Appx. Temp -5° C (f= 1.0)
Alt 12788 ft (3875 M)
Dip .97(sqrt 12788) = -110'
refraction by pub 249 table 6 = -55'
Total corr.: Upper Limb S.D.+Dip+Ref. = -181' (-3° 1')
note-there is no coriolis correction since a bubble octant wasn't used.
