mapping

This module provides base class for the mappings/patterns

class ska_dishln_pointing_device.mapping_scan.mapping.BaseScanMapping(pattern_name: str, component_manager, logger: Logger)

Bases: object

Base class for all scan mappings/patterns

extract_target_from_config()

Method to set the received ra and dec in the pointing groups field key

get_offset_in_rad(x: float, y: float) → tuple

Return the offset in radian

get_projection() → List[Union[str, Any]]

This method returns the projection name and projection alignment :return: projection name, projection alignment :rtype: List

get_radec_from_plane_to_sphere() → Tuple[float, float]

Convert plane coordinates to RA/Dec using spherical projection.

Returns:

A list containing the calculated RA and Dec coordinates in string.

Return type:

List[str]

set_target_and_start_process()

Generate program track table for normal scans.

Parameters:

• scan_parameters (dict) – A dictionary containing scan parameters.

• scan_id (str) – A string representing the scan ID.

Returns:

A dictionary containing the program track table.

Return type:

dict

set_trajectory_and_duration()

Create Trajectory Object and set duration

setup_observation_target() → None

point_mapping

Module for generating program track table for normal scans

class ska_dishln_pointing_device.mapping_scan.point_mapping.FixedMappingScan(pattern_name: str, component_manager, logger: Logger)

Bases: BaseScanMapping

FixedMappingScan class inherits from BaseScanMapping class. It is used to generate program track table for normal scans.
