READ Terr
READ Terr [vlist]Tell QDP/PLT which vectors have two-sided errors. It takes three columns to specify a vector with two-sided errors. The first column is the central value, the second column (which must be positive) specifies the upper bound, and the third column (which must be negative or zero) specifies the lower bound.
Example: READ Serr 1 READ Terr 2 1. .1 2. +.1 -.2This would be read as 1.0 ± 0.1 and 2.0+0.1-0.2. Note: In fitting, non-positive errors are ignored; thus the first error of two-sided errors should be positive.
