Baffled by DSLR tutorial
I am going though the Calibration:Beginner dslr tutoral for AIP4Win and things went very well until steps 4 and 5. Very little makes sense at this point.
From Step 4:
'Type the instrument magnitudes for your check stars in the yellow cells of the “Check I Mag” column and for your variable star in the yellow “I Mag” column cells.'
Check Star(s)? There are multiple check stars? I understood only one star was labeled as such, the others are comps. What are /where do the values come from that are exampled?
Based on the supplied tutorial image's, just how many instruments mags. should there be for the variable?
From Step 5:
Where do these entries in the 'Images' columns come from? I don't see any of these in the sample data.
Help clarifying this would be appreciated.
The yellow 'Check I Mag' and 'I Mag' columns appear each to be samples of single objects. If so which objects and how were multiple samples derived?
