(1) QC exclusions

Samples flagged QARTOD suspect (3) or fail (4) are dropped before pressure binning. The denominator is the count of finite input samples before binning, so the percentage is not distorted by binning's own reduction in point count.

A variable's exclusions are not all its own: the whole-cast soak / on-deck trim flags the same pre-descent and post-recovery scans on every variable, so a variable can be excluded here without its own gross-range or spike test having raised anything.

commentSame value for downcast and upcast profiles of the same cast.
source_data_mode N_PROF <U1 OceanSITES data mode of the source cast for this profile —— 8
1 attr
commentThe source cast's own data_mode (P provisional, D delayed-mode) — a per-profile fact about the source file, beside source_stage and source_tracking_id, not this compiled file's own mode. When the global data_mode is 'M' the casts genuinely differ, and this variable resolves which data is in which mode (the OceanSITES <PARAM>_DM obligation).
source_file N_PROF <U21 source per-cast filename this profile was compiled from —— 8
1 attr
commentFilename only (see the global 'source' attribute for the naming convention); the absolute root is deliberately not recorded, as it is a local, perishable path. Distinguishes casts that share a number — e.g. a plain cast and its lettered sibling.

flag_values[0 1 2 3]
flag_meaningsunknown converted soak_flagged qc_calibrated
commentBest-available stage for this cast at compile time: 1 = raw converted, 2 = soak/deck flagged, 3 = QC and calibration. 0 = unknown: an unsuffixed flat file assumed to be stage 1 by the compatibility shim, which does not state its own stage. Casts can be at mixed stages early in a cruise.
source_tracking_id N_PROF <U36 tracking_id of the per-cast file this profile was compiled from —— 8
1 attr
commentThe compiled file has its own tracking_id (global attr); this names the specific instance of each source cast file, so the lineage back to the CNV is readable per profile. Empty for a source file that predates the tracking_id.

(4) Sensor catalog

One dimensionless variable per distinct physical sensor; all provenance lives in its Attributes (model, serial, calibration date, vocabularies). No data, so no type, units, or value range.
