- Many labels have
  <lid_reference>urn:nasa:pds:context:instrument_host:dart.spacecraft</...>
which should be
  <lid_reference>urn:nasa:pds:context:instrument_host:spacecraft.dart</...>
- Suggestion: beyond bundle.xml and collection*.xml, add lid_reference to target



bundle.xml
- Please change this lid_reference
  urn:nasa:pds:context:target:asteroid.didymos
to
  urn:nasa:pds:context:target:asteroid.65803_didymos
- Suggestion: add lid_references to spacecraft and instrument
- For the rest of PDS, bundle.xml needs Citation_Information/doi. I don't know
what SBN does.

data_dracocal/calibration/*.xml
- Lines 77-79:
  <Target_Identification>
    <name>Bias Calibration File</name>
    <type>Calibration</type>
THe last value "Calibration" is invalid. Probably use "Calibrator"
If you want to add a lid_reference, perhaps
  urn:nasa:pds:context:target:calibrator.test_image
The files calibrator.* in https://pds.nasa.gov/data/pds4/context-pds4/target/
have possible LIDs.

data_dracocal/data_dracocal_collection.csv
- This should be named collection.csv or collection_inventory.csv, per the
PDS4 Standards, Section 2B.2.2.2, and the Data Provider's Handbook,
sections 4.3.1 and 4.3.2

Note that the only other file in this collection that references target
Didymos does it right, dart_0717892213_00957_01_geo.xml

logical_identifier, which is illegal:

"Hardware" is invalid. Perhaps use "Calibrator" or "Equipment".

data_dracoraw/commissioning/2021/336/dart_0376144597_01640_01_raw.metadata
- No label references this file, which is bad. If it's intended to be there,
perhaps another File_Area_Observational_Supplemental to the .xml

data_dracoraw/commissioning/2021/336/dart_0376144597_01640_01_raw.xml

data_dracoraw/commissioning/2021/3555/dart_0377785806_05467_01_raw.xml
- The frame around the data is float 32767.0, but this file has
  <missing_constant>-32768</missing_constant>
  <invalid_constant>4095</invalid_constant>
  <not_applicable_constant>-32767</not_applicable_constant>
so the actual data with values like 241.0 get washed out. Should the .fits
be filled with -32767, or should one of the Special Constants be set to 32767
or something else including ignore?
- The orientation of the .png is vertically flipped w.r.t. pds4_viewer's
display of this file (with the previous bullet taken care of).

data_dracoraw/cruise/2022/022/dart_0380520865_14915_01_raw.xml
- The data is not framed, but the vertical orientation of the .png is still
vertically flipped w.r.t. pds4_viewer's display of this file.
