Data for: The Surface Distributions of the Production of the Major Volatile Species, H2O, CO2, CO and O2, from the Nucleus of Comet 67P/Churyumov-Gerasimenko throughout the Rosetta Mission as Measured by the ROSINA Double Focusing Mass Spectrometer

The file MIRO_Columns.txt contains the column densities and their uncertainties corresponding to the results published previously in the paper by Marshall, D.W., Hartogh, P. Rezac, L. von Allmen, P., Biver, N., Bockelée-Morvan, D., Crovisier, J., Encrenaz, P. Bulkis, S. Hofstadter, M. Ip, W.-H., Jarchow, C. Lee, S., Lellouch, E. 2017. Spatially resolved evolution of the local H2O production rates of coet 67P/Churyumov,Gerasimenko, from the MIRO instrument of Rosetta. Astronomy & Astrophysics 603, A87. The format containes space delimited columns corresponding to Date, UT time, Heliocentric Distance (AU), column density (cm^-2), column density error (cm^-2).

文件 MIRO_Columns.txt 存储了与 Marshall, D.W. 等人于 2017 年发表的论文《基于罗塞塔号 MIRO 仪器的彗星 67P/丘留莫夫-格拉西缅科局部 H2O 生成速率的空间分辨演化》所发布的结果相对应的柱密度及其不确定性。该格式包含空格分隔的列，分别对应日期、协调世界时（UTC）时间、日心距离（天文单位）、柱密度（cm^-2）和柱密度误差（cm^-2）。
