Critique of XGRS Data Submissions to the PDS Mea Culpa: For the time I was able to devote to this review, I was unable to read any of the data files. XRS Data -------- 1. I found the browse facility for the XRS data to be extremely useful to overview the whole set. A suggested improvement on the presentation is to add a plot to the right of the colored spectrograms that collapses the time axis to plot counts versus channel. 2. A lien on the XRS level 2 data is that the level 1 set should be improved so that: the channel scale is computed by energy; the time axis should be converted from frame # to time of day; counts should be counts per unit time and energy; and a new set should be added to allow conversion from counts/time/energy in each of the three Eros-pointing proportional counters to counts per unit solar fluence as a function of energy. 3. I suggest that the data for the ~9 large solar flares could be augmented by choosing a comparable number of large flares when the XRS was not pointed at Eros. Also choose a representative sample of SEP events. Also include spectra of estimated uncertainties. 4. I saw no laboratory calibration data of sources (including 55Fe). These spectra should be documented and archived. Also, were any calibration data measured for energetic electron and ion backgrounds? Judging from the flare activity as evident in the solar pointing X-ray sensor many SEP events occurred during the time period on NEAR which occurred at solar maximum. 4[sic]. There are many clerical errors in the archived data. a. In the readme.txt file the thicknesses of all windows have the wrong units - I guess that they should be in mils not meters. In any case they should be converted to metric units. b. The same information in the browse files is repeated in CDs nxeros_2001 through nxeros_2012 regardless of the data specified in the browse.lbl file. In one case (nxeros_2012) the stop date is earlier than the start date. I suspect the number of CDs required for the XRS data can be reduced considerably if dupli- cation is eliminated. c. In each of the 2001 through 2012 CDs the colored spectrograms and footprint plots are duplicated, .html information is also on xrsbrowse.html 5. I did not see any report of anomalies yet the only data for the Sun was from the GRS proportional counter. 6. Was there any discussion of how charge-particle background was handled? (need the laboratory calibration spectra) 7. When the data analysis is finished the abundances of Mg, Al, Si, Ca, S and Fe need to be archived with their estimated uncertainties. GRS Data -------- 1. I have not been able to overview the archived data but from the description only asteroid pointing channel spectra are archived. I think level 2 data should include both asteroid and non-asteroid pointing spectra given as a function of energy & counts/GCR proxy/time. Also include calibrated uncertainties. 2. Any future analysis will require the archival of all laboratory calibration data (energy & angle) measured befor the launch. 3. If use of the O and Fe lines in the Gamma-ray data is to be melded in with the XRS data, some way of estimating the flux of galactic casmic rays will be needed. A separate GCR flux proxy then should be included in the archive. 4. All elemental abundances derived from the expanded Gamma-ray spectrum should be archived with uncertainties.
