Sample interview questions: What steps do you take to ensure the validity and accuracy of your astrometric data?
Sample answer:
- Calibration and Verification: Calibrating astrometric instruments using known reference stars with precise positions to correct for systematic errors and distortions. Verifying the accuracy of measurements through redundant observations and comparisons with independent data sets.
- Error Estimation: Quantifying uncertainties in astrometric data by analyzing statistical noise, systematic errors, and measurement precision. Establishing error bars and confidence intervals to assess the reliability of data and prevent overinterpretation.
- Data Quality Assessment: Implementing quality control checks to identify outliers, corrupted data, and inconsistencies. Manually inspecting data to detect potential errors and verify the validity of measurements.
- Astrometric Modeling: Constructing astrometric models to account for telescope aberrations, atmospheric refraction, and other env… Read full answer
