nectarchain.trr_test_suite.utils.err_sum

err_sum(err_a, err_b, cov_a_b=0)

Computes the square root of the sum of the squares of err_a and err_b, plus twice the covariance cov_a_b.

This function is used to calculate the combined error of two values, taking into account their individual errors and the covariance between them.

Args:

err_a (float): The error of the first value. err_b (float): The error of the second value. cov_a_b (float, optional): The covariance between the two values. Defaults to 0.

Returns:

float: The combined error.
