/* ** ** 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 59338.246116 0.000521 0.13889 0.01050 0.99444 0 17.71904 0.46722 16.34291 0.43089 2.46093 0.17444 2.26972 0.16087 59338.247134 0.000498 0.14913 0.01140 0.99419 0 16.88599 0.46816 15.67542 0.43459 2.51818 0.17940 2.33763 0.16654 59338.248115 0.000483 0.15436 0.01201 0.98802 0 16.69015 0.47161 15.44594 0.43643 2.57629 0.18680 2.38380 0.17285 59338.249090 0.000492 0.15904 0.01214 0.98824 0 16.24642 0.46040 15.01367 0.42545 2.58376 0.18316 2.38811 0.16929 59338.250054 0.000472 0.15564 0.01196 0.99387 0 16.99265 0.48072 15.77456 0.44626 2.64473 0.18890 2.45513 0.17535 59338.251075 0.000550 0.13229 0.01034 0.98421 0 16.95025 0.44430 15.71801 0.41200 2.24242 0.16509 2.07980 0.15312 59338.252065 0.000440 0.16568 0.01283 1.00000 0 17.21445 0.50711 15.80845 0.46571 2.85211 0.20422 2.62017 0.18760 59338.253000 0.000495 0.15487 0.01212 0.99415 0 16.08488 0.46009 14.88146 0.42566 2.49110 0.18153 2.30505 0.16799 59338.253946 0.000451 0.16623 0.01285 1.00000 0 16.64523 0.49163 15.33932 0.45305 2.76695 0.19762 2.54956 0.18210 59338.254866 0.000469 0.16678 0.01284 1.00000 0 16.02302 0.46821 14.80736 0.43266 2.67225 0.19038 2.46750 0.17579 59338.256128 0.000793 0.16149 0.00967 0.96350 0 16.62385 0.36819 15.35562 0.34007 2.68455 0.14938 2.47990 0.13798
