    Hello Dennis,
    
    Your comments are deeply appreciated! Thank you.
    
    This is the  link to the new updated version, corrected as per your
    suggestions:

    Here are my itemized comments to your suggestions (which I took into
    consideration
    when correcting the paper, to a large extent) --

      L41: “for event definition purposes” was a bit mysterious to me. I
      think the time is needed to reject signals not associated with a
      real beam-beam crossing, right? 
    
    
    Corrected. The language was indeed awkward, I've corrected it now.
    
    L62: I
      found myself curious about the specific type of interpolation. Was
      this a spline, polynomial, something else?
    
    It's actually linear -- it's the fastest, and given the factor 15
    oversampling we expected it to be adequate.
    And, I did a numerical comparison with a spline, and they match at
    more than 6 decimal places, so our expectation was
    correct. It's enough precision. I've added add a couple of words to
    elucidate that.

L91: would it be useful to give a citation or definition for the “modified Landau distribution” ?

    Done. There is a seminal paper where this functional form is derived
    for Landau, I've enclosed the citation.

L125-126: is there any potential issue with using a training sample with a distribution over energies that may not match the distribution of energies to which the ML method will be applied? For example, if the samples from the test beam are roughly similar for each energy, but in real data this will be a steeply falling distribution. Or is this mitigated by the template shape changing minimally with E?

    The dependency on the mix was there but not steep. I did some
    empirical tweaking of the mix and
    picked the one which produced the most precise inference. I have
    added a couple of words
    to clarify that situation.

L178 and L181: There is no Figure 4 - should this be Figure 3?

    This was a leftover from Tim and I tweaking the graphics, panels
    etc, it's corrected now.

Ref. 4: the ROOT authors have a requested citation - https://github.com/root-project/root/#cite .

    Done, thank you.

You might check if there is some specific way Refs. 5-9 like to be cited, rather than just as a website.

    These URLs are really the best sources. There is a strong technical
    angle to these, and this will be lost in
    a paper reference. Any conference presentation based on this won't
    be as good. If the referee requests that
    I'll change this.
    
    Thank you for the work you invested in reviewing this paper. Please
    let Tim and I know if you have further comments.
    We would like to close out by COB tomorrow, Friday, since the
    weekend is the deadline for the submission.
    
    Best regards,
    
    Maxim

Dear All,

Thanks to Dennis for pointing out my omission of not including the line numbers.
I created an additional copy with these included:

Please let me know if anything else needs fixing.
Best regards,

Hello Maxim,

Could you please circulate a version with line numbers? It may also be useful to copy the EMCal list.
