/* ** ** 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 56647.142738 0.000382 0.17318 0.01350 0.99242 0 18.75975 0.55983 17.43430 0.52022 3.24888 0.23387 3.02007 0.21741 56647.143517 0.000396 0.16086 0.01246 0.97810 0 19.72478 0.56356 18.35797 0.52450 3.17294 0.22842 2.95245 0.21254 56647.144292 0.000379 0.17077 0.01320 0.96947 0 19.65603 0.57414 18.31940 0.53510 3.35666 0.24020 3.12841 0.22386 56647.145033 0.000362 0.18293 0.01425 1.00000 0 18.75248 0.57460 17.47713 0.53552 3.43039 0.24568 3.19708 0.22897 56647.145771 0.000376 0.17220 0.01334 0.99231 0 19.30350 0.57053 17.99050 0.53173 3.32405 0.23806 3.09795 0.22187 56647.146538 0.000391 0.15825 0.01229 0.99259 0 20.03505 0.57110 18.67198 0.53225 3.17057 0.22901 2.95487 0.21343 56647.147330 0.000402 0.15266 0.01192 1.00000 0 19.83547 0.55886 18.48665 0.52086 3.02799 0.22061 2.82208 0.20561 56647.148103 0.000370 0.16634 0.01291 1.00000 0 20.03825 0.58916 18.67534 0.54908 3.33320 0.23933 3.10650 0.22305 56647.148870 0.000396 0.15855 0.01216 1.00000 0 19.90739 0.56906 18.47536 0.52805 3.15627 0.22474 2.92931 0.20855 56647.149680 0.000414 0.15490 0.01184 0.99301 0 20.08283 0.56101 18.54575 0.51807 3.11089 0.22123 2.87305 0.20435 56647.150484 0.000391 0.16103 0.01245 0.99259 0 19.97425 0.57052 18.53018 0.52927 3.21649 0.23113 2.98477 0.21448 56647.151202 0.000327 0.19088 0.01516 1.00000 0 19.62870 0.61883 18.29436 0.57676 3.74676 0.27316 3.49201 0.25459 56647.151873 0.000344 0.18155 0.01402 0.99160 0 20.19983 0.61163 18.82694 0.57006 3.66719 0.26043 3.41795 0.24273 56647.152611 0.000394 0.15348 0.01193 0.99265 0 20.58438 0.58053 19.01813 0.53633 3.15935 0.22878 2.91814 0.21133 56647.153392 0.000388 0.16331 0.01267 0.99254 0 19.62644 0.56850 18.20743 0.52735 3.20517 0.23072 2.97465 0.21414 56647.154179 0.000399 0.15912 0.01221 0.99275 0 19.73358 0.56650 18.31082 0.52567 3.13997 0.22335 2.91232 0.20716 56647.155056 0.000477 0.18851 0.01247 0.99394 0 19.70094 0.51500 18.22634 0.47646 3.71385 0.22569 3.43415 0.20871
