The γ -ray flux points are one day binned in units of 10 − 6 ph cm − 2 s − 1 , Swift -XRT (0.3–10 keV) flux points are in units of 10 − 11 erg cm − 2 s − 1 , and Swift -UVOT fluxes are in units of 10 − 15 erg cm − 2 s − 1 A − 1 . The vertical dotted lines with horizontal gray arrow headed lines represents the time slots corresponding to three flux states, viz. ‘flaring state (FS)’, ‘plateau state (PS)’ and ‘quiescent state (QS)’ for which time averaged SEDs are obtained. The vertical solid gray region corresponds to VHE flaring time of 3C 279. ( 78 )
