IVOA: Calibration Level Mismatch
A standard for Data level definitions is needed. IVOA provides a definition they want to see used, however, this definition does not match up with the data Level usage commonly used at KIS.
The definitions we use currently are (to the best of my knowledge): 0. Raw Data
- Calibrated/ Reconstructed Data
- Scientific information such as Dopplergrams
Definitions of Calibration Levels by IVOA
Solarnet on Data Levels
The concept of "data level" is often used to label data with a particular degree of processing, from raw data up to complex data products. However, definitions of data levels are extremely instrument-/mission-/pipeline-dependent, and not very useful in terms of explaining what processing has been applied. This concept is useful, however, to ensure that files with different processing level have unique file names. For this reason, the keyword LEVEL may be used, as a string value to capture sub-levels such as quick- look versions.
