Spectrograph Detector Focus Alignment Images with Confidence Interval Code

A collection of images captured to align a spectrograph sensor in its best-focus position. The dataset includes all computer code to compute the best-focus position and determine confidence intervals for the solution, providing a statistical measure of precision. It was authored by Travis W. Sawyer and includes an example IPython notebook for guidance.

Use Cases

• Calibrating spectrograph detector arrays based on the included focus alignment images.
• Evaluating measurement precision using the provided confidence interval calculation code.
• Developing statistical methods for optical alignment based on the documented approach.
• Teaching focus alignment and uncertainty quantification techniques using the included example notebook.

Strengths

• Includes all computer code for calculating best-focus position and confidence intervals.
• Provides an example use document in IPython notebook format for step-by-step guidance.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
