/* ** ** 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 54559.240565 0.000281 0.31830 0.01169 1.00000 0 69.34931 1.25191 64.41411 1.16278 22.07399 0.70606 20.49794 0.65554 54559.241112 0.000266 0.33508 0.01247 1.00000 0 68.95706 1.28483 64.64127 1.20442 23.10591 0.74465 21.65973 0.69804 54559.241670 0.000292 0.30299 0.01116 1.00000 0 69.24632 1.22650 64.91972 1.14986 20.98107 0.67723 19.67015 0.63491 54559.242252 0.000289 0.32216 0.01186 1.00000 0 66.14252 1.20761 62.00986 1.13216 21.30851 0.68083 19.97714 0.63829 54559.242825 0.000284 0.32842 0.01227 1.00000 0 65.71210 1.21517 61.60731 1.13926 21.58149 0.70035 20.23339 0.65660 54559.243386 0.000278 0.33167 0.01228 1.00000 0 66.74686 1.23452 62.57755 1.15741 22.13810 0.71037 20.75522 0.66600 54559.243962 0.000298 0.30319 0.01112 1.00000 0 67.73122 1.19996 63.50149 1.12502 20.53574 0.65958 19.25328 0.61839 54559.244555 0.000295 0.31730 0.01158 1.00000 0 66.20717 1.19029 62.07142 1.11594 21.00775 0.66735 19.69546 0.62566 54559.245154 0.000304 0.29199 0.01072 1.00000 0 69.14372 1.20454 64.45121 1.12267 20.18915 0.65266 18.81208 0.60813 54559.245759 0.000301 0.30457 0.01126 1.00000 0 66.49773 1.18493 62.34226 1.11089 20.25320 0.65578 18.98717 0.61479 54559.246361 0.000301 0.30836 0.01126 1.00000 0 66.80262 1.19050 62.55223 1.11476 20.59952 0.65687 19.28584 0.61495 54559.246957 0.000295 0.30643 0.01130 1.00000 0 67.88505 1.21174 63.30504 1.12998 20.80232 0.67104 19.39093 0.62549 54559.247547 0.000295 0.31315 0.01152 1.00000 0 66.72269 1.20036 62.22606 1.11942 20.89391 0.67044 19.48132 0.62507 54559.248135 0.000292 0.31446 0.01158 1.00000 0 66.84760 1.20768 62.67190 1.13224 21.02101 0.67487 19.70790 0.63272 54559.248725 0.000298 0.30237 0.01109 1.00000 0 68.22031 1.20752 63.95703 1.13206 20.62790 0.66299 19.33882 0.62155 54559.249309 0.000286 0.32309 0.01198 1.00000 0 66.46779 1.21642 61.89460 1.13260 21.47501 0.69250 19.99877 0.64477 54559.249897 0.000301 0.32219 0.01192 1.00000 0 63.56322 1.16158 59.27504 1.08318 20.47936 0.65846 19.08161 0.61356 54559.250490 0.000292 0.30796 0.01147 1.00000 0 68.22151 1.22634 63.18480 1.13571 21.00964 0.68519 19.45389 0.63432 54559.251098 0.000315 0.28775 0.01055 1.00000 0 67.53950 1.16657 63.32170 1.09371 19.43462 0.62832 18.22094 0.58909 54559.251717 0.000304 0.31182 0.01144 1.00000 0 65.37599 1.17153 61.12061 1.09525 20.38544 0.65280 19.05252 0.61011 54559.252319 0.000298 0.30189 0.01111 1.00000 0 69.03159 1.22278 64.03749 1.13428 20.83997 0.67207 19.32711 0.62319 54559.253042 0.000425 0.30701 0.00960 1.00000 0 65.52161 0.99014 61.02045 0.92209 20.11553 0.55033 18.72624 0.51228
