Fields

Field	Type	Required	Description
bounds	BoundsSerializationModel	yes	The region where this field can be evaluated. The bbox of this region is grown by half a pixel on all sides and then used to remap coordinates to [-1, 1]x[-1, 1], which is the natural domain of a 2-d Chebyshev polynomial.
butler_info	ButlerInfo | null	no	Information about the butler dataset backed by this file.
coefficients	InlineArray	yes	Coefficients for a 2-d Chebyshev polynomial of the first kind, as a 2-d matrix in which element [p, q] corresponds to the coefficient of T_p(y) T_q(x).
field_type	string	no
indirect	array of any	no	Serialized nested objects that may be saved or read more than once.
metadata	object	no	Additional unstructured metadata.
min_read_version	integer	no	Smallest reader major that can interpret this tree.
schema_version	string	no	Data-model schema version of this tree (major.minor.patch).
unit	Unit | null	no	Units of the field.
