Mercury's Impact structure inventory

This data set display an inventory of impact structures larger than 100 km on Mercury. The gravity measurements were determined using a amore precise approach of calculating the avearge of multiple profiles along the impact structure. Variables: ID: Identification number or the name of the impact structure. Diam (km): The diameter of the impact structure in kilometers. Lon: Central longitude. Lat: Central latitude. Id_source: Primarly identification source ( Gravity data / DTM/ Mosaic model). Certainity: Grade of certainity ( Certain, probable or tentative). Class : Geomorphological classification (complex, central peak basins, peak ring basin, multi ring basins, modified basin). Terraces: Presence of terraces. Rim: Rim preservation state. Depth [km]: Depth measurements in km. D/d: Depth to diameter ratio. Filling: Presence of volcanis infill. Smooth plains: Filling classified as part of the smooth plains. Bouguer_center: Measured Bouguer anomaly (mGal) of LOS gravity model (Goossens et al., 2022) associated with the center of the impact structure. Bouguer_outer: Measured Bouguer anomaly (mGal) of LOS gravity model (Goossens et al., 2022) associated with the outer area of the impact structure. Bouguer_rimcrest: Measured Bouguer anomaly (mGal) of LOS gravity model (Goossens et al., 2022) associated with the rim area of the impact structure. Bouguer_contrast: Bouguer anomaly contrast (mGal). Stdev_center: Standard deviation of the Bouguer anomaly in the center. Stdev_outer: Standard deviation of the Bouguer anomaly in the outer area. Stdev_rimcrest: Standard deviation of the Bouguer anomaly at the rimcrest. CC: Crater counts of N(20). Area: The area of the basin in km². N(20)/Area: Value that refelcts the relative age of impact structures. CT_center: Measured crustal thickness (km) associated with the center of the impact structure. CT_outer: Measured crustal thickness (km) associated with the outer area of the impact structure. CT_rim: Measured crustal thickness (km) associated with the rim area of the impact structure. Temperature [K]: Crustal temperature of impact structures at 39.4km depth at 3.0 Ga.本数据集收录了水星上直径大于100千米的撞击构造清单。本次重力测量采用更为精准的分析方法：沿撞击构造采集多条剖面数据并计算其平均值，以此确定重力场参数。 变量： ID：撞击构造的识别编号或名称 Diam (km)：撞击构造的直径，单位为千米 Lon：中心经度 Lat：中心纬度 Id_source：主要识别数据源（重力数据 / 数字地形模型（DTM） / 镶嵌模型） Certainty：确定度等级（确定、大概率或暂定） Class：地貌学分类（复杂撞击坑、中央峰盆地、峰环盆地、多环盆地、改造型盆地） Terraces：是否存在阶地 Rim：环边保存状态 Depth [km]：深度测量值，单位为千米 D/d：深径比 Filling：是否存在火山充填 Smooth plains：充填物归类为平滑平原 Bouguer_center：与撞击构造中心相关的LOS重力模型（Goossens等人，2022）测得的布格异常，单位为毫伽 Bouguer_outer：与撞击构造外围区域相关的LOS重力模型（Goossens等人，2022）测得的布格异常，单位为毫伽 Bouguer_rimcrest：与撞击构造环脊区域相关的LOS重力模型（Goossens等人，2022）测得的布格异常，单位为毫伽 Bouguer_contrast：布格异常差值，单位为毫伽 Stdev_center：中心区域布格异常的标准差 Stdev_outer：外围区域布格异常的标准差 Stdev_rimcrest：环脊区域布格异常的标准差 CC：N(20)撞击坑计数 Area：盆地面积，单位为平方千米 N(20)/Area：反映撞击构造相对年龄的指标 CT_center：与撞击构造中心相关的实测地壳厚度，单位为千米 CT_outer：与撞击构造外围区域相关的实测地壳厚度，单位为千米 CT_rim：与撞击构造环边区域相关的实测地壳厚度，单位为千米 Temperature [K]：3.0 Ga时，深度39.4km处撞击构造的地壳温度，单位为开尔文
