[ferret_users] Averaging Values are Mismatching



Dear ferreters
                  I am getting some error when I a averaging the values. it is mismatching with the ferret calculation. Suppose I have average the values like

list/precision=7 D20[x=60.25:61.25@ave,y=-6.25:-5.25@ave,l=1]
 its value has come 60.39426

when I have listed the values as
list/precision=7/x=60.25:61.25/y=-6.25:-5.25 D20[l=1]
             VARIABLE : TEMP[Z=@LOC:20]
                        Z=-0.02:5500
             FILENAME : soda_d20_1958_2010_indpac.nc
             SUBSET   : 3 by 3 points (LONGITUDE-LATITUDE)
             TIME     : 15-JAN-1958 00:00
                60.25E    60.75E    61.25E 
                 61        62        63
 5.25S / 70:  64.47244  65.52505  67.76488
 5.75S / 69:  59.62996  59.87644  61.27785
 6.25S / 68:  55.80148  55.17461  55.52123

I  calculated analytical and It is giving  60.56349

When I have taken corresponding I and J values, I got as

list/precision=7 D20[i=61:63@ave,j=68:70@ave,l=1]
Its values has come   60.56349

 

Could you please suggest me, how to solve this problem

With regards
Abhishek
