/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56772.930814 0.000249 0.22881 0.01816 0.98837 0 22.27638 0.75787 20.34572 0.69217 5.09710 0.36554 4.66432 0.33453 56772.931332 0.000269 0.20744 0.01634 1.00000 0 22.54777 0.73649 20.69343 0.67587 4.67731 0.33534 4.29112 0.30764 56772.931841 0.000240 0.23885 0.01888 0.98795 0 22.26265 0.77187 20.52461 0.71161 5.31735 0.37764 4.90090 0.34807 56772.932341 0.000260 0.20482 0.01614 1.00000 0 23.29692 0.76066 21.50812 0.70225 4.77157 0.34222 4.40519 0.31594 56772.932874 0.000272 0.20094 0.01549 1.00000 0 23.32302 0.74426 21.53085 0.68707 4.68647 0.32893 4.32635 0.30365 56772.933386 0.000240 0.23646 0.01878 0.98795 0 22.22837 0.77400 20.51990 0.71451 5.25601 0.37518 4.85204 0.34635 56772.933907 0.000281 0.19378 0.01513 1.00000 0 22.92872 0.72456 21.16676 0.66888 4.44315 0.31716 4.10172 0.29279 56772.934468 0.000281 0.19739 0.01566 1.00000 0 22.44086 0.71932 20.58245 0.65970 4.42960 0.32145 4.06465 0.29493 56772.935027 0.000278 0.20236 0.01588 1.00000 0 22.22064 0.71637 20.51227 0.66129 4.49649 0.32167 4.15073 0.29693 56772.935553 0.000249 0.22598 0.01809 0.98837 0 22.39290 0.76473 20.51210 0.70050 5.06042 0.36647 4.63138 0.33534 56772.936068 0.000266 0.21228 0.01659 1.00000 0 22.25744 0.73363 20.54658 0.67724 4.72481 0.33483 4.36163 0.30909 56772.936604 0.000269 0.20213 0.01609 0.98925 0 22.93622 0.74103 21.09404 0.68147 4.63620 0.33733 4.26377 0.31020 56772.937159 0.000286 0.18594 0.01445 1.00000 0 23.76084 0.73189 21.73842 0.66959 4.41803 0.31530 4.04519 0.28864 56772.937700 0.000255 0.21216 0.01667 0.98864 0 23.34967 0.76654 21.55562 0.70765 4.95382 0.35361 4.57318 0.32644 56772.938201 0.000246 0.21340 0.01701 1.00000 0 23.51041 0.78442 21.70308 0.72412 5.01704 0.36326 4.63138 0.33534 56772.938725 0.000278 0.21134 0.01651 1.00000 0 21.42571 0.70534 19.77851 0.65111 4.52801 0.32088 4.17990 0.29622 56772.939277 0.000275 0.19788 0.01546 0.98947 0 23.33478 0.74155 21.35495 0.67861 4.61743 0.32962 4.23263 0.30213 56772.939844 0.000292 0.19456 0.01523 0.99010 0 22.32208 0.70068 20.52235 0.64416 4.34310 0.31134 3.99074 0.28610 56772.940380 0.000243 0.21582 0.01692 1.00000 0 24.01360 0.79648 22.16725 0.73524 5.18270 0.36808 4.78421 0.33978 56772.940909 0.000286 0.18273 0.01431 1.00000 0 23.99099 0.73630 22.01451 0.67563 4.38393 0.31576 4.01691 0.28934 56772.941447 0.000252 0.21140 0.01676 1.00000 0 23.27115 0.76979 21.48014 0.71055 4.91963 0.35452 4.54100 0.32724 56772.942029 0.000330 0.20693 0.01456 1.00000 0 22.81320 0.66663 20.95011 0.61219 4.72075 0.30207 4.33357 0.27729
