/* ** ** 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 59944.256363 0.000226 0.13734 0.01074 1.00000 0 39.39654 1.05414 36.33704 0.97227 5.41088 0.39772 4.99549 0.36713 59944.256831 0.000243 0.13367 0.01018 1.00000 0 38.70677 1.01380 35.59108 0.93212 5.17403 0.37004 4.76132 0.34051 59944.257297 0.000223 0.14232 0.01089 1.00000 0 39.18178 1.06906 36.27465 0.98974 5.57620 0.39865 5.16258 0.36907 59944.257746 0.000226 0.13929 0.01059 1.00000 0 39.68044 1.06545 36.73275 0.98630 5.52716 0.39298 5.11658 0.36378 59944.258212 0.000240 0.13143 0.00995 1.00000 0 39.51878 1.02887 36.58354 0.95245 5.19415 0.36930 4.80835 0.34187 59944.258692 0.000240 0.13483 0.01030 0.98795 0 38.88516 1.02468 35.99466 0.94851 5.24273 0.37590 4.85302 0.34796 59944.259161 0.000229 0.13476 0.01048 1.00000 0 39.69942 1.05620 36.74798 0.97768 5.34991 0.39100 4.95218 0.36193 59944.259635 0.000246 0.12432 0.00955 1.00000 0 40.87147 1.03863 37.56422 0.95448 5.08121 0.36850 4.67332 0.33885 59944.260145 0.000263 0.11858 0.00911 1.00000 0 39.32473 0.98281 36.40185 0.90976 4.66302 0.33892 4.31644 0.31373 59944.260645 0.000237 0.13057 0.00991 1.00000 0 40.31129 1.04839 37.31430 0.97044 5.26353 0.37533 4.87222 0.34743 59944.261137 0.000255 0.12258 0.00952 1.00000 0 39.25692 1.00275 36.31001 0.92731 4.81194 0.35273 4.45058 0.32620 59944.261614 0.000223 0.14779 0.01147 1.00000 0 37.68862 1.06129 34.65163 0.97591 5.57004 0.40266 5.12170 0.37021 59944.262098 0.000260 0.12374 0.00931 1.00000 0 38.90939 0.98078 36.01661 0.90787 4.81458 0.34145 4.45662 0.31606 59944.262590 0.000231 0.13939 0.01065 1.00000 0 38.68480 1.04095 35.65065 0.95932 5.39246 0.38550 4.96898 0.35523 59944.263038 0.000217 0.14839 0.01141 1.00000 0 38.73516 1.07368 35.76222 0.99124 5.74777 0.41215 5.30597 0.38044 59944.263478 0.000223 0.14144 0.01104 1.00000 0 38.80394 1.06301 35.92068 0.98403 5.48861 0.40114 5.08081 0.37133 59944.263955 0.000255 0.12613 0.00972 1.00000 0 38.45111 0.98853 35.38401 0.90963 4.84967 0.35243 4.46360 0.32442 59944.264450 0.000240 0.13478 0.01027 1.00000 0 38.66946 1.02015 35.74416 0.94296 5.21180 0.37272 4.81869 0.34461 59944.264977 0.000286 0.11349 0.00850 1.00000 0 38.79039 0.93510 35.68914 0.86030 4.40214 0.31220 4.05148 0.28733 59944.265616 0.000353 0.14295 0.00865 0.98361 0 40.27893 0.85507 37.28756 0.79157 5.75793 0.32646 5.33030 0.30221
