/* ** ** 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 58195.103937 0.000391 0.25827 0.02142 0.97778 0 29.83669 1.11586 11.41825 0.42708 7.70601 0.57045 2.95218 0.21836 58195.104707 0.000379 0.22219 0.01871 0.98473 0 33.54965 1.17681 13.25403 0.46487 7.45455 0.57069 2.94895 0.22573 58195.105436 0.000350 0.25153 0.02131 0.96694 0 32.56886 1.21404 13.00148 0.48429 8.19220 0.62311 3.26725 0.24838 58195.106165 0.000379 0.23106 0.01884 0.98473 0 33.46481 1.18217 13.13303 0.46377 7.73241 0.56809 3.03521 0.22297 58195.106967 0.000422 0.21076 0.01739 0.96575 0 33.13765 1.11708 12.89457 0.43440 6.98396 0.52585 2.72323 0.20477 58195.107789 0.000399 0.21402 0.01777 0.96377 0 34.80846 1.18459 13.41466 0.45647 7.44964 0.56418 2.87308 0.21754 58195.108573 0.000385 0.22846 0.01863 0.99248 0 33.22130 1.17544 12.98408 0.45937 7.58979 0.55769 2.96623 0.21790 58195.109351 0.000394 0.23086 0.01924 0.99265 0 31.60217 1.13326 12.30642 0.44135 7.29566 0.54878 2.84426 0.21387 58195.110075 0.000330 0.26519 0.02225 0.99123 0 32.97775 1.25855 12.86578 0.49090 8.74537 0.65342 3.41442 0.25498 58195.110766 0.000362 0.24044 0.02017 0.96800 0 34.11765 1.23030 13.13363 0.47359 8.20321 0.62117 3.15802 0.23911 58195.111594 0.000466 0.18419 0.01501 0.96894 0 33.99407 1.06956 13.37101 0.42067 6.26147 0.47084 2.46138 0.18508 58195.112444 0.000385 0.23804 0.01908 0.99248 0 32.53770 1.15998 12.70640 0.45295 7.74530 0.55606 3.02356 0.21707 58195.113229 0.000399 0.21515 0.01757 1.00000 0 33.19381 1.14680 13.11448 0.45296 7.14168 0.52835 2.82382 0.20886 58195.113992 0.000365 0.22257 0.01847 1.00000 0 34.89887 1.22255 13.68208 0.47939 7.76748 0.58424 3.04742 0.22915 58195.114736 0.000379 0.20829 0.01741 0.99237 0 35.36390 1.19026 14.05820 0.47312 7.36606 0.56344 2.92626 0.22400 58195.115543 0.000428 0.23667 0.01804 1.00000 0 32.55643 1.09838 12.83675 0.43307 7.70510 0.52655 3.03810 0.20757
