pleiades.sammy.parameters.data_reduction module

Data class for card 08::data reduction parameters.

class pleiades.sammy.parameters.data_reduction.DataReductionParameter(*, name: Annotated[str, MaxLen(max_length=5)], value: float, flag: VaryFlag = VaryFlag.NO, uncertainty: float | None = None, derivative_value: float | None = None)

Bases: BaseModel

Container for a single data reduction parameter entry.

Each parameter has: - A name (5-char alphanumeric) - A value - A flag indicating whether it should be varied - Optional uncertainty - Optional derivative value

name: str

value: float

flag: VaryFlag

uncertainty: float | None

derivative_value: float | None

validate_name() → DataReductionParameter

Validate name field is not empty and fits format.

classmethod from_line(line: str) → DataReductionParameter

Parse parameter from a fixed-width format line.

Parameters:

line – Input line

Returns:

Parsed parameter

Return type:

DataReductionParameter

Raises:

ValueError – If line is invalid or required data missing

to_line() → str

Convert the parameter to a fixed-width format line.

Returns:

Formatted line

Return type:

str

model_config = {}

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].

class pleiades.sammy.parameters.data_reduction.DataReductionCard(*, parameters: List[DataReductionParameter])

Bases: BaseModel

Container for a complete data reduction parameter card set (Card Set 8).

This class handles: - Header line - Multiple parameter entries - Trailing blank line

parameters: List[DataReductionParameter]

classmethod is_header_line(line: str) → bool

Check if line is a valid header line.

classmethod from_lines(lines: List[str]) → DataReductionCard

Parse a complete data reduction card set from lines.

Parameters:

lines – List of input lines including header

Returns:

Parsed card set

Return type:

DataReductionCard

Raises:

ValueError – If no valid header found or invalid format

to_lines() → List[str]

Convert the card set to a list of lines.

Returns:

Lines including header and parameters

Return type:

List[str]

model_config = {}

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
