SG_Raw_Data & Residual_Gravity_EQ1-4

For SG raw data:<br>The first column represents the recorded voltage of the iGrav001 superconducting gravimeter. The second column represents the atmospheric pressure measurements. The last column represents the theoretical tide at the SG location.The rest of the columns represent the instrument's hardware system status.The ResidualGravity_EQ#1-4 files contain residual gravity data about 2 hours before and after the EQ#1-4 onsets, with a 1-sec sample rate.

针对SG原始数据：第一列为iGrav001型超导重力仪（superconducting gravimeter）记录的电压数据；第二列为大气压力观测数据；最后一列为测站SG处的理论潮汐数据；其余各列均为该仪器的硬件系统状态参数。ResidualGravity_EQ#1-4文件包含了EQ#1-4地震事件发震前后约2小时的剩余重力数据，采样率为1秒。
