These look OK to me. Our visibilities are already scaled by the validity
(=weight) factor. This is a problem we originally had with FITLD before I
came to visit you.
Assuming the second step is multiplying the weights by the integration
time, I guess it doesn't really make any difference as we don't do mixed
integration time correlation (but I guess we cannot rule it out). But I
guess it doesn't cause any harm so is OK.
So basically, I think what FITLD does is correct to JIVE data.
