Hello Kei,

Thank you for all the corrections to the f1(1285) paper.  I have
implemented almost all of them.  The new draft of the paper will be
ready in a few more days, I hope, and I will post the revised version.
Below are a few remarks.

Reinhard

Good idea.  I changed it to have a block of equations with one number.

Left it as is because I like it.  Maybe the PRC editor will change it.

Yes.  The events are binned differently but not scaled.

We're ignoring the line.  Ryan is supposed to be remaking this figure.

This figure was completely replaced with a better one.

This paragraph was rewritten to be simpler.

Removed the possibly-confusing clause "Since..."  One of the hallmarks
of eta vs f1 is whether or not the thing decays to (and hence can be
made by) a photon.

Left this out.  No change.

We have struggled for a long time to change the line spacing in the
\longtable environment without success.  Same for trying to change the
font size.

That's all for now...
