Each row in the table gives the measured noise power for one received polarization during one time interval. This was Table 2 in [SIMPSON&TYLER1999]. Carriage-Return Line-Feed 10 0 68 MEASUREMENT NUMBER 1 2 ASCII_String 3 A composite field in which the first character gives the polarization ('R' for right circular polarization or 'L' for left circular polarization) and the remaining two characters are the measurement number. For example, 'R12' is the twelfth measurement in right circular polarization. TARGET 2 8 ASCII_String 3 The target at which the antenna was pointed during the measurement. Choices include: AMB antenna disconnected; receiver connected to ambient load CTR antenna pointed at center of Moon LIM antenna pointed at polar region on the Moon (which was near the limb, as seen from Earth) SKY antenna pointed at (dark, or presumably empty) sky START TIME 3 13 ASCII_Integer 5 second The start time of the measurement. STOP TIME 4 19 ASCII_Integer 5 second The stop time of the measurement. NUMBER OF POINTS 5 25 ASCII_Integer 3 The number of independent measurement points within the interval -- usually equal to the number of seconds in the interval since one point was taken each second. ATTENUATOR SETTING 6 29 ASCII_Real 4 decibel The attenuator setting for the measured polarization during the interval. The attenuators can only be set to integral values of dB; fractional values here indicate minor adjustments based on self-consistency tests within the Clementine data set. MEAN NOISE POWER 7 34 ASCII_Real 9 Mean value of the NUMBER OF POINTS measurements. The value is proportional to power, but the scale factor is not known. STANDARD DEVIATION 8 44 ASCII_Real 9 Standard deviation of the NUMBER OF POINTS measurements for which the mean was given in the previous column. The value is proportional to power, but the scale factor is not known. ADJUSTED MEAN 9 54 ASCII_Real 6 Mean value from Column 7 scaled by the attenuation (Column 6) to give the equivalent value had the attenuator been set to zero. The scale factor is the antilog of the value in Column 6 divided by 10. WEIGHTED MEAN 10 61 ASCII_Real 6 Weighted average of successive ADJUSTED MEAN values for the same TARGET, where weighting is based on the NUMBER OF POINTS in each interval. The following weighted means were computed R02 and R03 R04 through R15 R16 and R17 R18 and R19 L02 and L03 L04 through L18 L20 and L21 In other cases the value in Column 9 was copied to Column 10. table2.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
