Hi Ansley,
Actually I have 2-d error data file which
looks like
name title I J K L
ERROR 1:360 1:180 ... 1:12
And I have CO2 data related to this error
CO2 1:360 1:180 ... 1:12
I am ploting CO2 curve in ferret
plot co2[x=@ave,l=1:12,y=-60:60@ave]
Now I want to plot error bar using the data 1
variable ERROR. This error data(data 1 ERROR)
is (sigma)**2 . I want to calulate the total
error like
total_error = (SUM(ERROR)/N)**1/2
here N I guess would be 180*360, am I right ?
SO can you please suggest me how to calculate
the total error in ferret for each month
using this formula, this would be error bar.
And finally I want to plot error bar (total
error) on the CO2 curve.
For more clarification I wrote formula in
word .doc file and I am sending you this
little word file.
Pls help.
Many thanks in advance,
Regards,
Yogesh
