How I fixed my Line OII data

[Earl]

As some of you may recall I had a set of subs where a line came down from a star to the ccd edge.

I gathered another 3 hours of data and it would still not caibrate out.

What did I do?

I duplicated all the data without the line (giving me a total of 36 600s subs) then calibrated the whole lot together and now the line has almost gone.

Can of worms but it worked!

That is a big improvement, well done. Great save!
