SDDS_0001 ========= - J-C. Liou notes that these data are not really of scientific value in and of themselves, but rather are useful in interpreting other Startdust data sets. aareadme.txt - There is an ellipsis on the final paragraph that should be replaced by real names. voldesc.cat - Syntax error, line 54 (comma at end of line). catalog/ -------- dataset.cat - Syntax error, line 174 - quotes inside quotes. - Note in the DATA_SET catalog file that this data set is intended to support the analysis of other Stardust data sets. Ideally, the other Stardust data set descriptions should also reference this data set. inst.cat - There are [TBD] notations in the text of the description. data/ ----- - The data cannot be interpreted without additional information. For example, the inst.cat file contains a filler paragraph under the "Location" subheading, and there are numerous [TBD] fields. Boris has some of this information, but not all of it (detailed AC description, for example). - The plots of the attitude rate columns look odd. Is there an explanation for the pathology of these variables? The signal seems to oscillate by the size of the quoted delta-value in the data set description. And what is the significance of the spikes that appear in the plots? For example, the s/c rate components show a point to point oscillation of +- 0.0002 rad/sec is this measurement noise? Highest detectable frequency, i.e. every other point. There are some significant (.001 rad/sec) events on top of this, but how does one interpret it? - For the small forces data, add error bars, or a note about precision, for the velocity measurements if possible. - Please include a table of relevant spacecraft parameters for the convenience of the users. Need to know some ephemeris info. *.fmt - UNIT should be omitted if it is not applicable. (UNIT = "N/A" means units of Newtons/Ampere or Newtons/Angstrom). - I don't see a definition for the quaternions listed here. Which quaternion formation convention is used here? *.tab - The header table contains unquoted string values. documentation ------------- - Add the following documentation: o Explanation of what happens to the angular momentum values when the spacecraft is hit by a particle o An explanation for the pathology of the angular momentum plots o An explanation for the repeated values in the last three columns in the telemetry file during the high data rate periods near encounter o A note that there are no cruise data, and why o Time of closest approach - Boris has offered to provide a description of how the two files comprising the dataset would be used together. This would be very helpful. index/ ------ index.lbl - Missing FORMAT statements. ASCII Tables object MUST have FORMAT statements.
