Our recorded observations are called.
trapecia [35]

Answer:  Raw data, perhaps.

Explanation:  I'm not certain what the question is seeking for an answer, but I would suggest "raw data" would be a reasonable choice.  It reflects the data was recorded, but not yet processed to provide a conclusion or observation.

If one were a bit snarky, other possiblities include

  • a pile of dung
  • my labmate's scrawls, or
  • the best web results I could find
