/* ** ** 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 56412.129429 0.000269 0.18079 0.01409 0.98925 0 26.67359 0.80413 23.90777 0.72071 4.82243 0.34644 4.32091 0.31040 56412.129964 0.000266 0.18211 0.01411 1.00000 0 26.72902 0.81449 23.95206 0.72985 4.86750 0.34663 4.36133 0.31061 56412.130523 0.000292 0.16678 0.01296 0.98020 0 26.53781 0.77355 23.95434 0.69824 4.42604 0.31878 3.99515 0.28774 56412.131110 0.000295 0.16368 0.01264 0.99020 0 26.62037 0.76983 24.02882 0.69488 4.35720 0.31190 3.93303 0.28154 56412.131726 0.000321 0.15004 0.01152 0.99099 0 26.66475 0.73832 24.06878 0.66644 4.00072 0.28638 3.61123 0.25850 56412.132334 0.000286 0.16842 0.01312 1.00000 0 26.28049 0.78040 23.72198 0.70443 4.42605 0.31878 3.99515 0.28774 56412.132939 0.000318 0.15227 0.01188 0.99091 0 26.30434 0.74079 23.74361 0.66868 4.00546 0.29129 3.61553 0.26294 56412.133650 0.000394 0.15016 0.01044 0.98018 0 26.87961 0.67231 24.26264 0.60686 4.03627 0.26177 3.64330 0.23628 56412.193276 0.000237 0.19629 0.01575 1.00000 0 27.94382 0.89830 24.38942 0.78395 5.48513 0.40325 4.78475 0.35184 56412.193782 0.000269 0.16641 0.01316 1.00000 0 28.96620 0.86037 25.35311 0.75296 4.82013 0.35313 4.21620 0.30890 56412.194349 0.000298 0.15796 0.01232 0.98058 0 28.46360 0.81320 24.69646 0.70554 4.49620 0.32619 3.89727 0.28267 56412.194971 0.000324 0.13896 0.01082 1.00000 0 28.70547 0.77984 25.17756 0.68400 3.98888 0.29117 3.49879 0.25539 56412.195622 0.000327 0.14659 0.01141 0.98230 0 27.59809 0.75885 24.20639 0.66559 4.04558 0.29451 3.54835 0.25832 56412.196253 0.000304 0.15315 0.01176 1.00000 0 28.28236 0.79888 24.82334 0.70117 4.33147 0.30940 3.80142 0.27153 56412.196846 0.000289 0.15919 0.01229 1.00000 0 28.58120 0.81928 25.08611 0.71910 4.54987 0.32622 3.99392 0.28636 56412.197408 0.000272 0.17834 0.01408 0.98936 0 27.22175 0.82602 23.88267 0.72470 4.85470 0.35379 4.25928 0.31040 56412.198131 0.000451 0.13417 0.00910 0.98718 0 28.24543 0.65311 24.79784 0.57339 3.78971 0.24153 3.32667 0.21202
