/* ** ** 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 55690.959340 0.000414 0.12491 0.01927 0.96503 0 13.37695 0.68398 5.71150 0.29067 1.67094 0.24326 0.71071 0.10321 55690.960251 0.000498 0.10658 0.01627 0.97093 0 13.58845 0.64033 5.51705 0.25999 1.44832 0.21027 0.58730 0.08528 55690.961122 0.000373 0.15528 0.02367 0.96899 0 12.43622 0.70528 5.15583 0.29237 1.93113 0.27318 0.80133 0.11333 55690.962040 0.000544 0.09270 0.01466 0.99468 0 12.95581 0.58623 5.46916 0.24734 1.20096 0.18198 0.50773 0.07677 55690.962934 0.000350 0.14884 0.02345 0.96694 0 13.31771 0.74206 5.58698 0.31114 1.98214 0.29219 0.82935 0.12206 55690.963651 0.000367 0.14710 0.02259 0.96850 0 12.98196 0.71736 5.47501 0.30234 1.90960 0.27361 0.80588 0.11548 55690.964464 0.000446 0.11809 0.01790 0.96753 0 13.72620 0.67777 5.64744 0.27882 1.62095 0.23237 0.66525 0.09533 55690.965214 0.000304 0.17237 0.02712 0.96190 0 13.23318 0.79740 5.59496 0.33708 2.28096 0.33151 0.97107 0.14101 55690.965856 0.000339 0.14823 0.02485 0.98291 0 13.13016 0.75112 5.38535 0.30805 1.94631 0.30671 0.79838 0.12583 55690.966554 0.000359 0.15275 0.02350 0.95968 0 13.01339 0.72644 5.43565 0.30323 1.98773 0.28495 0.83296 0.11936 55690.967283 0.000370 0.14178 0.02233 0.98438 0 13.05843 0.72689 5.39902 0.30055 1.85137 0.27274 0.77011 0.11334 55690.968038 0.000385 0.13415 0.02023 0.96992 0 13.71982 0.71679 5.78383 0.30208 1.84058 0.26034 0.77649 0.10981 55690.968822 0.000399 0.12452 0.01965 0.97826 0 13.78526 0.71418 5.69504 0.29494 1.71653 0.25589 0.71104 0.10607 55690.969516 0.000295 0.16557 0.02629 1.00000 0 13.69599 0.81839 5.75660 0.34386 2.26769 0.33358 0.95132 0.14001 55690.970150 0.000339 0.13196 0.02145 0.98291 0 14.66652 0.78694 6.20312 0.33268 1.93534 0.29693 0.81654 0.12517 55690.970813 0.000324 0.16156 0.02558 0.97321 0 12.57102 0.73272 5.53186 0.32234 2.03102 0.29904 0.89022 0.13102 55690.971678 0.000541 0.10567 0.01489 0.97326 0 14.79708 0.63439 6.18437 0.26508 1.56355 0.20982 0.65377 0.08762
