Left plots: red are targets, blue are telluric. Observed mags are calculated from median value of green chip. Zeropoint gives overall throughput: bigger number is more throughput.
First spatial plots: circles are objects, squares are tellurics, crosses are sky fibers. Colors give deviation of observed mag from expected 2MASS mag using the median zeropoint; red is brighter
Second spatial plots: circles are sky fibers. Colors give sky line brightness relative to plate median sky line brightness
