ABotPhases
Archaeobotanical data at the phase level, therefore only for phases that have this type of data. RecoveryMethod1, 2, 3 etc have no intrinsic differences, and the order is irrelevant. This is simply to allow for multiple recovery methods at a single phase.
Column name	Data type	Column description
AbotMeshSizeMin	decimal	Minimum Mesh size (mm) used in archaeobotanical recovery
ABotNumberOfContexts	smallint	Number of distinct 'pits' or 'contexts' from which ABot data has been counted. Used to calculate unbiquity. Surface scatter would count as a single pit.
Notes	varchar
PhaseID	varchar	Please see the detailed description of the 'Phases' table.
RecoveryMethod1	varchar
RecoveryMethod2	varchar
RecoveryMethod3	varchar
RecoveryMethod4	varchar
Volume	smallint	Volume (litres) of the soil extracted for sampling.
