#Transparency 1=Clear 2=Fog 3=Thin cloud <2 [mag loss <2 mag.] 4=Thick cloud >2 [mag loss >2 mag. 5=Broken opaque cloud [that is, observed thru gaps in the cloud] 6=Star faint 7=By averted vision
#Transparency: 1
#Stability _=unstated 1=Steady 2=Slight flickering 3=Strong flickering 
#Stability: 2
#Comments: 1) Target signal saturated. 2) I doubt about the time precision because the IOTA-VTI probably failed to synchronize to the GPS time
