Relative J‐band flux (arbitrary units), plotted as a function of J‐band seeing FWHM (arcseconds), for 2MASS J19020417−0454110 (blue) and 2MASX J03320335+3658101(green) Cal‐PSWDB data. Error bars are suppressed. Black dashed segmented lines illustrate the dependence of apparent magnitude with seeing. These sources are extreme examples of (anti‐)correlated variations observed in our sample, with J‐band r‐correlation statistics of 0.63 and −0.82, respectively. See § 3.5 for discussion.
