/* ** ** 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 59130.649043 0.000130 0.31542 0.02738 1.00000 0 42.11720 1.78368 26.93814 1.11554 13.28479 1.00661 8.61843 0.63875 59130.649694 0.000521 0.24231 0.00877 1.00000 0 54.61207 0.87197 45.12907 0.72036 13.23306 0.42993 10.92587 0.35489 59130.650675 0.000460 0.28621 0.01050 1.00000 0 54.67846 0.95036 43.40368 0.75428 15.64929 0.50536 12.43188 0.40140 59130.651600 0.000466 0.28083 0.01047 0.99379 0 54.00269 0.93924 43.46257 0.75564 15.16536 0.49983 12.21606 0.40250 59130.652573 0.000506 0.25298 0.00922 1.00000 0 55.47964 0.90303 44.34648 0.72167 14.03503 0.45755 11.21804 0.36566 59130.653580 0.000501 0.27160 0.00985 1.00000 0 53.61746 0.90355 42.28448 0.71255 14.56250 0.46793 11.47690 0.36873 59130.654575 0.000495 0.25957 0.00943 1.00000 0 56.47208 0.93510 44.63910 0.73910 14.65831 0.47388 11.58157 0.37440 59130.655536 0.000466 0.27163 0.01008 1.00000 0 54.85353 0.93488 44.76105 0.76285 14.89991 0.49088 12.15916 0.40059 59130.656470 0.000469 0.27778 0.01031 1.00000 0 54.54565 0.94524 43.50909 0.75395 15.15179 0.49713 12.09113 0.39667 59130.657422 0.000483 0.27833 0.01012 1.00000 0 54.54596 0.93163 42.83819 0.73162 15.18186 0.48705 11.92446 0.38256 59130.658383 0.000477 0.26941 0.00983 1.00000 0 55.84433 0.94066 44.50878 0.74956 15.04525 0.48685 11.98158 0.38764 59130.659613 0.000752 0.26695 0.00793 1.00000 0 55.42907 0.75050 44.11341 0.59710 14.79657 0.39133 11.78327 0.31138
