IRAC High Precision Photometry
This is an investigation of the actual precision reached for published, single epoch, IRAC observations. Plots are normalized at a binning size of 1. The dashed black line is photon noise limited. The dashed grey line is 2 (1.5) times the photon noise limit for ch1 (2). The third plot is a zoom in on ch2.
These plots are incomplete!! If you have data you would like to add to this plot, please email the SSC Helpdesk.
