SG_Raw_Data & Residual_Gravity_EQ1-4

For SG raw data: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.
