Liens for New Horizon SDC data sets (Dec 2016 peer review)
----------------------------------------------------------

Certification Status: Not certified.  Delta review for the final archive submission.


There also appear to be spurious RALPH data in some of the housekeeping files.


file: 'aareadme.txt'
--> Under "Whom to contact...": Mihaly's name is mis-spelled, and is duplicated two lines in a row

file: 'calib/calinfo.txt'
--> typo: 'calibation' => 'calibration'

files: 'calib/sdc_cal_matrix_*.tab'
--> typos: 'Celcius' => 'Celsius'

file: 'catalog/dataset.cat'
--> typo: "New Horizon" => "New Horizons" in second paragraph of Data Set Overview section in DATA_SET_DESC
--> typo: missing 'than' in "that detection limit is lower **than** earlier in the mission"

file: 'catalog/sdc.cat'
--> There is a statement (in catalog/sdc.cat) that they haven't detected particles over 3 micometers since early 2014. 
--> --> 1) How significant is this? Does it point to a larger systematic problem? Is it becoming less sensitive? 
--> --> 2) This note is weird for this documentation because generally particles are referred to by their charge and mass, not by size, and I don't think the equation for the conversion is anywhere in the documentation. 

files: 'data/*/*.lbl'
--> typo in QUALITY_FLAG description: 'intials' => 'initials'
--> Generally unclear how the housekeeping data is used for calibration (I probably missed a doc that described this?)
--> --> For instance, some HK data includes "Conversion: polynomial coefficients:" - how is this used?
--> --> HK data from other instruments are included (but not used)?

files: '*-3-*/data/*/*.lbl'
--> Question about velocity used:
--> --> In data/...sci.lbl files, the "IMP_VEL" parameter is given as 
=======================
              IMP_VEL = 1E-3 x SQRT(G x Msun x (1-beta) / R)                  
                                                                              
            where                                                             
              G = Gravitational constant = 6.77384E-11                        
              Msun = Mass of the Sun, kg                                      
              beta = 0 = correction for solar pressure                        
              R = Heliocentric distance, m                                    
                                                                              
            Units consistent with G (m**3 kg**-1 s**-2)
=======================
--> --> 1) Why not provide the value of Msun?
--> --> 2) The sdc_ssr.pdf states (p.5) that the value used for the velocity calculation for the grain mass ("MASS" parameter) is the s/c velocity
--> --> 3) Working backwards from the IMP_VEL values, these don't correspond to the s/c distance
--> --> 4) What are these values? Are they used to get the MASS parameter?

file: 'nh-p-sdc-3-pluto-v2.0/data/20160119_031574/sdc_0315748362_0x700_sci.fit
--> This file is not formatted correctly.  It appears to be an intermediate step between raw and calibrated.  Has CHARGE_DATA object instead of expected CALIBRATED_DATA object.

file: 'nh-p-sdc-*-pluto-v2.0/document/seq_sdc_pluto.tab'
--> Why is there only one entry here?  For example the plutocruise data sets have several listed.
