Originally titled "I have lots R and" and posted to the Observations & Campaign Reports under the thread "New Bright Nova in SGR: PNV J18202726-2744263" = Nova Sgr 2012 No. 4. Moved here and retitled to remove confusion and to place in the most appropriate forum.
I have a lot of R and I data taken from the time of outburst on this nova. I'd like to be able to calibrate it. The fields are flattened and bias-corrected. So, all I'm missing to transform it out of differential photometry are some standards.
