    2 ** We are resubmitting our article "Pan-STARRS Photometric and
    3    Astrometric Calibration" after addressing suggestions raised by the
    4    referee.  We thank the referee for detailed comments and
    5    suggestions.  Below are our responses to the referee's suggestions.
    6    In the response below, our responses are preceeded by "**".

    12 The paper "Pan-STARRS Photometric and Astrometric Calibration" by
    13 Magnier et al. describes the calibration of a major modern sky survey.
    14 The paper is well written and provides sufficient technical detail to not
    15 only for the reader to understand what was done, but also to inform
    16 future surveys. Given this legacy aspect, my only major comment is
    17 that it would be prudent to discuss the performance of Pan-STARRS
    18 calibration in comparison to other major optical surveys, such as SDSS,
    19 DES and HSC surveys. Such a discussion would illuminate all your
    20 advances and provide direction for future work. My other, much more
    21 minor comments are listed below.

    24    Conclusion section to put this article in the context of other
    25    recent and future surveys.

    63 - page 9, right column, 2nd paragraph: this clipping procedure sounds
    64 like an ad hoc hocus pocus; can you provide at least some statistical
    65 justification (e.g. what is the distribution model you had in your mind)?
    66 perhaps even more ad hoc procedure is assigning weights of 10x their
    67 default; why 10 and not 5, or 50, or?

    78 - comment about proper motions after introducing eqs. 21-24 is not
    79 entirely correct because a lot of your observations are far from the
    80 galactic plane and thus are sensitive to the asymmetric drift effects
