/* ** ** 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 57376.203327 0.000420 0.14555 0.01124 0.99310 0 25.06797 0.68810 18.93051 0.51877 3.64868 0.26328 2.74462 0.19795 57376.204120 0.000373 0.16996 0.01317 1.00000 0 22.75569 0.67937 18.19077 0.54300 3.86763 0.27647 3.09336 0.22107 57376.204904 0.000411 0.14691 0.01163 0.99296 0 23.18653 0.64838 18.74427 0.52410 3.40628 0.25232 2.75157 0.20379 57376.205734 0.000420 0.14823 0.01133 1.00000 0 23.17270 0.64410 18.56245 0.51600 3.43477 0.24447 2.75071 0.19579 57376.206570 0.000417 0.14788 0.01153 0.99306 0 23.04862 0.63891 18.61160 0.51590 3.40849 0.24846 2.75246 0.20063 57376.207366 0.000379 0.16519 0.01291 0.96947 0 23.55675 0.68305 18.74681 0.54355 3.89126 0.28251 3.09773 0.22490 57376.208197 0.000451 0.13633 0.01039 0.98718 0 23.83306 0.63039 19.01703 0.50299 3.24923 0.23222 2.59119 0.18518 57376.209067 0.000420 0.13989 0.01119 0.99310 0 23.76895 0.65179 19.06328 0.52271 3.32496 0.24977 2.66905 0.20034 57376.209892 0.000405 0.15678 0.01206 0.99286 0 23.04995 0.65718 18.30776 0.52198 3.61372 0.25827 2.87081 0.20516 57376.210670 0.000373 0.16102 0.01267 0.99225 0 23.73660 0.69271 19.00463 0.55460 3.82196 0.27936 3.05936 0.22360 57376.211426 0.000382 0.16672 0.01282 0.99242 0 23.10811 0.67640 18.46236 0.54039 3.85250 0.27392 3.07671 0.21876 57376.212207 0.000399 0.15952 0.01218 0.99275 0 22.91098 0.65274 18.43374 0.52519 3.65485 0.25882 2.94058 0.20825 57376.213020 0.000414 0.15896 0.01229 0.97203 0 22.56344 0.64068 17.97207 0.51031 3.58676 0.25804 2.85776 0.20558 57376.213850 0.000417 0.16897 0.01314 0.97917 0 20.90151 0.61589 16.67359 0.49130 3.53177 0.25405 2.81723 0.20266 57376.214779 0.000512 0.15349 0.01080 0.98993 0 22.68238 0.57889 18.07114 0.46120 3.48153 0.22825 2.77338 0.18183 57376.261104 0.000382 0.15932 0.01250 0.99242 0 20.75130 0.60022 18.95997 0.54834 3.30617 0.24120 3.02220 0.22046 57376.261865 0.000379 0.15524 0.01208 0.98473 0 21.68758 0.61297 19.85290 0.56108 3.36673 0.24402 3.08297 0.22344 57376.262609 0.000365 0.16309 0.01271 0.98413 0 21.34452 0.61688 19.55988 0.56532 3.48112 0.25198 3.18944 0.23087 57376.263361 0.000388 0.14852 0.01170 0.99254 0 21.53123 0.60723 19.72202 0.55624 3.19784 0.23515 2.93157 0.21557 57376.264171 0.000422 0.13733 0.01075 0.99315 0 21.36702 0.57625 19.58718 0.52825 2.93424 0.21572 2.68895 0.19773 57376.265039 0.000446 0.13494 0.01046 1.00000 0 20.58616 0.54689 18.94492 0.50329 2.77793 0.20240 2.55647 0.18626 57376.265861 0.000376 0.15778 0.01216 0.98462 0 21.36334 0.60840 19.66191 0.55994 3.37065 0.24146 3.10217 0.22223 57376.266648 0.000411 0.14552 0.01117 1.00000 0 20.95934 0.57935 19.20511 0.53083 3.05007 0.21851 2.79632 0.20032 57376.267467 0.000408 0.14669 0.01138 0.98582 0 21.08141 0.57992 19.31458 0.53131 3.09234 0.22440 2.83085 0.20545 57376.268274 0.000399 0.15617 0.01218 0.99275 0 20.10058 0.57208 18.41842 0.52419 3.13903 0.22788 2.87217 0.20845 57376.269119 0.000446 0.13331 0.01014 0.98701 0 21.39234 0.55808 19.69535 0.51381 2.85175 0.20376 2.62553 0.18760 57376.269987 0.000422 0.13958 0.01092 0.97260 0 21.43759 0.57221 19.64851 0.52444 2.99231 0.22011 2.74576 0.20191 57376.270971 0.000561 0.14668 0.00943 0.98969 0 21.89414 0.50371 20.09475 0.46228 3.21135 0.19287 2.94566 0.17689
