Target Object Data
#1
Greg,

Would you be so kind as to explain the notation you use for the target object data -- particularly for emission nebulae? Example from M27:

SBr(V) 23.1 SBr® 23.2 SBr(total) 22.3
SII[6717]/Ha 0.09 NII[6584]/Ha 0.97

Am guessing SBr(V) and SBr® are¬†photogrametic brightness measures. But I don't understand the ratio calculations or the units.

Thanks,

Greg Latiak
