The accepted work-around to this requirement is that projects provide “human readable” HTML versions of the documents with PNG/JPEG versions of the figures. I have no objection to providing the NH project with a waiver to this requirement. However, if this is the case, then this waiver should be noted in the ERRATA.TXT file in the root directory of the volume. Problem remains, suggestion for ERRATA note is still a viable solution NH-SWAP Review S. Joy

I find data from 2008-05-28 to 2010-07-17. nh.cat gives the mission phase boundaries as: PLUTOCRUISE 2007-06-27 to 2014-12-31 The text should state the time range of the archive and explain why that differs from the time range of the mission phase. You could consider pointing users at seq_swap_plutocruise.tab in the DOCUMENT directory for a list of the time intervals that instrument was operating and the activities being performed. Corrected ►Required reading section /CATALOG/ directory: There are no files corresponding to NH_TRAJECTORY.* In the /DOCUMENT directory there are files called “nh_mission_trajectory. /DOCUMENT/directory: There are no files corresponding to PAYLOAD.* In the /DOCUMENT directory there are files called “payload_ssr.” /CALIB/directory: Does not list the actual calibration tables, only the CALINFO.TXT file No change, accepted as is Please add SWAP_CAL.* to the list in the DOCUMENT directory NH-SWAP Review S.

I suggest renaming quat_axyz_instr_to_j2k.asc to quat_axyz_instr_to_j2k.txt and correcting the pointer in the PDS label. Lien rejected 2) There are no “ASCII” versions of these documents.

Neither the text nor file label provide a description of the width parameter. ► Page 11, Background Subtraction "are scaled by the distance to the Sun squared and those scaled rates (counts*R2/sample) are stored in…" Please provide the units for the distance to the Sun (AU vs. km will make a difference in the calculation).

Recommendations The SWAP raw (nh-x-swap-2-plutocruise-v2.0) and calibrated (nh-x-swap-3-plutocruise-v2.0) datasets are both scientifically useful as is and they should be certified as such by the PDS as part of this review. There are minor documentation errors and PDS standards errors that should be either corrected or noted in an ERRATA.TXT file at the root level of the archive “volume”. NH-SWAP Review S. Joy
