Pre-Flight Load Calibration Table                                             
                                                                              
This handwritten table gives the pre-flight load calibration data for the     
Apollo 16 Lunar Self-Recording Penetrometer (LSRP) flight unit, lunar drum    
S/N 2003. The tests were done on 19 April 1972.  The upper part of the table  
gives the load calibration.  The first column gives the index number          
corresponding to the initial stting on the LSRP.  The second column, "REF.",  
gives the initial angle  (degrees, minutes, seconds) read on the drum. The    
following columns are for different loads put on the LSRP.  The entries in    
the columns give the reading on the drum (azimuth) and the difference         
between that and the original reading.  Listed at the bottom of the columns   
are the loads for that column in kilograms and Newtons, the average           
variation in degrees, minutes and in decimal degrees, and a row titled "AVG   
mm" which gives the average drum circumferential deflection.  These numbers   
were used to create the pre-flight load calibration table                     
A16_SMSS_72_M016936_041, page D-1.                                            
                                                                              
The upper part of this table is very difficult to read due to poor            
quality of the original paper copy and/or microfilming.  To improve the       
quality, NASA National Space Science Data Center (NSSDC) personnel            
rewrote the upper part of the table, lines 1-23, using the original           
microfilm and the known relationships of the values.  The table was           
scanned and included in this archive as A16_SMSS_72_M016936_044.
