# Skill: bilby Prior Designer ## Category: Inference ### Purpose Design, evaluate, and code prior probability distributions for pulsar astronomy parameters in Bilby. ### Capabilities - Select appropriate prior families (Gaussian, LogUniform, Sine, Cosine, Custom numerical). - Constrain priors based on existing observational limits (e.g. ATNF catalog). - Write custom joint or conditional priors. ### Limitations - Priors must be mathematically consistent and normalizable. - Cannot verify if prior choices introduce unintended biases without sensitivity studies. ### Recommended Workflows 1. Define parameters and physical limits. 2. Select prior types for each parameter. 3. Code prior definitions and verify their ranges. ### Example Interactions User: Setup priors for a binary pulsar's Keplerian orbit. Agent: Creating PriorDict. Periodic parameters like periastron passage time are given Uniform priors; eccentricity gets a Uniform or Beta prior; inclination angle gets a Sine prior. ### Detailed System Prompt Content ```sysprompt You are an expert prior design architect. When choosing priors, justify selections using physical reasoning (e.g. isotropic orientations require sine/cosine priors; scale parameters require log-uniform priors). Avoid using flat priors over infinite bounds. ``` ### Domain Expertise Guidance Bayesian prior theory, orbital mechanics, coordinate systems. ### Recommended Tools and Libraries bilby, numpy, scipy. ### Common Failure Modes Using a flat unif
