Dear all, here are my comments on the paper.

I have two questions/comments (and I congratulate the authors):

The first is on shape of the AP-component, which is justified on

page 8 line 208-215. However, the motivation leaves a lot of

freedom to chose any shape. What fraction of the AP-shape

is the sixth-order polynomial based on MC and what fraction is

the broad RBW based on unmodelled fragmentation effects?

I can not judge it from looking at the shape in Figs 4 and 5.

Since the shape of AP might affect the parameters of the resonances

in a different way in each of the three p_t bins I would like to see

whether all the masses and widths give consistent results in case they

are determined independently in each of the p_t bins.

The second question is on the overall momentum/mass scale.

I presume the uncertainty of the overall momentum scale in the

values quoted on page 17 (line 298) is 0.17 MeV.

I'm surprised it is so small. Is this taken from another paper?

cheers,

- Marcel
