Calibration Skill

What problem does it solve?

This Skill provides expert guidance and tools for performing accurate radio interferometer calibration, correcting for instrumental and atmospheric distortions in astronomical data.

Core Features & Use Cases

• Automated Calibration Pipelines: Leverages CASA tasks within a managed Python environment for robust calibration.
• Optimized Presets: Utilizes pre-defined, empirically tested configurations for DSA-110 data, simplifying complex calibration steps.
• Flux Calibration Guidance: Clearly distinguishes bandpass calibration from absolute flux calibration, providing methods for accurate flux scaling.
• Self-Calibration: Implements iterative self-calibration routines to refine calibration solutions and improve image quality.
• GPU Acceleration: Supports optional GPU acceleration for gain application, speeding up processing for large datasets.
• Use Case: A radio astronomer needs to calibrate raw visibility data from the DSA-110. They can use this Skill to apply the default calibration preset, ensuring accurate corrections for bandpass and gain variations, and then optionally run self-calibration to further enhance the data before imaging.

Quick Start

Use the calibration skill to apply the default calibration preset to your observation data.
