      <description>This table is a hand-typed reproduction of the        
        original handwritten chart of the raw data read from the penetrometer     
        drum returned to Earth and the reduced data for the LSRP Soil Mechanics   
        run designated index number 8.  The chart is on frames 22 and 23 (pages   
        B-8 and B-9) of the Soil Mechanics Experiment Report of APOLLO 16 LSRP    
        Data, May 1972.  The corresponding JPEG images and text descriptions for  
        these frames are:                                                         
        document/a16_lsrp_data_report_hires/A16_SMSS_72_M016936_022.JPG,                                   
        document/a16_lsrp_data_report_hires/A16_SMSS_72_M016936_022.ASC,                                   
        document/a16_lsrp_data_report_hires/A16_SMSS_72_M016936_023.JPG, and                               
        document/a16_lsrp_data_report_hires/A16_SMSS_72_M016936_023.ASC.                                   
        
        On the scanned chart, the conversion from Drum Load to Drum               
        Circumference Deflection is given as 'x .5542', and the conversion of     
        Delta Drum Depth reading to Actual Penetration Depth is 'x 31.3'.         
        However it appears the multipliers used to derive drum circumference      
        deflection from drum load were 0.542 for the first 24 rows of the data    
        and approximately 0.553 for rows remaining rows.  The data provider       
        recomputed the conversion from drum load to drum circumference            
        deflection for all rows using the multiplier given on the original        
        chart, 0.5542.  The resulting table is included in this archive           
        as A16_SMSS_72_M016936_022_REC.TAB; its PDS label is                      
        A16_SMSS_72_M016936_022_REC.LBL.</description>
