adam_core.coordinates.cometary module

class adam_core.coordinates.cometary.CometaryCoordinates(table: Table, **kwargs: int | float | str)

Bases: Table

q

A column for storing 64-bit floating point numbers.

e

A column for storing 64-bit floating point numbers.

i

A column for storing 64-bit floating point numbers.

raan

A column for storing 64-bit floating point numbers.

ap

A column for storing 64-bit floating point numbers.

tp

A column for storing 64-bit floating point numbers.

time

A column which represents an embedded quivr table.

Parameters:

• table_type – The type of the table to embed.

• nullable – Whether the column can contain null values.

• metadata – A dictionary of metadata to attach to the column.

covariance

A column which represents an embedded quivr table.

Parameters:

• table_type – The type of the table to embed.

• nullable – Whether the column can contain null values.

• metadata – A dictionary of metadata to attach to the column.

origin

A column which represents an embedded quivr table.

Parameters:

• table_type – The type of the table to embed.

• nullable – Whether the column can contain null values.

• metadata – A dictionary of metadata to attach to the column.

frame

StringAttribute represents a string which is stored as UTF-8 bytes in Table metadata.

Parameters:

default – The default value for this attribute. If no default is provided, then the attribute must be set whenever constructing a table that uses it.
