/* ** ** 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 56010.150676 0.000414 0.15146 0.01167 1.00000 0 19.81670 0.55224 18.29017 0.50971 3.00153 0.21552 2.77056 0.19894 56010.151515 0.000425 0.15778 0.01210 0.99320 0 18.89423 0.53578 17.36226 0.49234 2.98113 0.21242 2.73757 0.19507 56010.152377 0.000437 0.15044 0.01170 0.99338 0 19.20183 0.53660 17.42695 0.48698 2.88877 0.20960 2.62137 0.19018 56010.153211 0.000396 0.16395 0.01269 0.99270 0 19.59047 0.56632 17.78019 0.51397 3.21177 0.23066 2.91316 0.20918 56010.153983 0.000376 0.18300 0.01422 0.98462 0 18.78933 0.57526 16.96002 0.51928 3.43850 0.24566 3.10689 0.22195 56010.154761 0.000402 0.16229 0.01258 0.98561 0 19.71371 0.56474 17.86010 0.51160 3.19931 0.23035 2.89562 0.20846 56010.155560 0.000396 0.16699 0.01277 0.99270 0 19.62459 0.56944 17.74005 0.51477 3.27715 0.23176 2.96457 0.20965 56010.156417 0.000460 0.14619 0.01127 0.97484 0 19.25556 0.52241 17.42217 0.47266 2.81493 0.20320 2.54643 0.18380 56010.157235 0.000359 0.18812 0.01450 0.98387 0 19.22156 0.58967 17.55867 0.53863 3.61593 0.25570 3.30476 0.23370 56010.158011 0.000417 0.17320 0.01334 0.98611 0 17.93298 0.53192 16.22751 0.48133 3.10608 0.22077 2.81109 0.19979 56010.158853 0.000425 0.15232 0.01164 0.98639 0 19.81210 0.54747 18.11290 0.50049 3.01776 0.21501 2.75645 0.19642 56010.159669 0.000391 0.16854 0.01353 1.00000 0 18.49020 0.55540 16.93633 0.50865 3.11627 0.23209 2.85735 0.21275 56010.160913 0.000854 0.14504 0.00808 0.99322 0 19.28341 0.38242 17.68560 0.35069 2.79680 0.14563 2.56588 0.13359
