Recalibration of the lunar chronology due to spatial cratering-rate variability - Data and code

CR_moon.csv: Relative cratering rate shown in Fig.2. The<strong> </strong>data are provided over the full range of latitudes and longitudes, with a 1-degree bin. cr_lefeuvre2011.txt: Relative cratering rate proposed by Le Feuvre and Wieczorek (2011). The<strong> </strong>data are provided over the full range of latitudes and longitudes, with a 1-degree bin. lunar_calib_points.csv: Table summarising the lunar chronology calibration points used in this study. Lagain_AA_convert_age.m: Matlab code converting model ages of Plutarch and Kirkwood craters from Neukum et al. (2001) chronology into the one presented in this study. The code also computes the chronology model from Le Feuvre and Wieczorek (2011) and the one presented in this study for different locations, and compares it with the Neukum et al. (2001) chronology.CR_moon.csv：图2中展示的相对撞击坑比率（relative cratering rate）数据，覆盖全经纬度范围，采用1度分箱格式存储。 cr_lefeuvre2011.txt：由Le Feuvre与Wieczorek（2011）提出的相对撞击坑比率数据，覆盖全经纬度范围，采用1度分箱格式存储。 lunar_calib_points.csv：汇总本研究中所用月球年代学校准点的表格。 Lagain_AA_convert_age.m：用于将Plutarch和Kirkwood撞击坑的模型年龄从纽库姆等人（Neukum et al.）2001年提出的年代学体系转换为本研究提出的年代学体系的Matlab代码。该代码还可针对不同地点计算Le Feuvre与Wieczorek（2011）的年代学模型以及本研究提出的年代学模型，并将其与纽库姆等人（Neukum et al.）2001年的年代学体系进行对比。
