# replicationbench / gw_nsbh__default_mbh - taskset: [replicationbench](https://harnessreport.com/tasks/replicationbench.md) - difficulty: easy - category: research - language: - runnable from the site: no - agent timeout: 3600s ## Results by harness _none yet_ ## Instruction ``` # default_mbh ## Description 68% CI on M_BH, default settings ## Instructions Report the 1-sigma (68%) credible interval on the minimum mass of a black hole, under the hierarchical inference setup. Measure this under default settings, assuming $\beta = 0$, the 'ZS' spin prior described in the paper, and all 4 LIGO events described in the paper. . Return the result in the list format [lower bound, median, upper bound]. ## Additional Instructions Unless otherwise specified, all posteriors should be computed using MCMC sampling and all quantities should be in source frame. All confidence intervals (i.e. 1-sigma) should be computed as credible intervals, using quantiles of the posterior distribution. ## Dataset Information **Datasets are available in `/assets` directory.** ## Execution Requirements - Read inputs from `/assets` (downloaded datasets) and `/resources` (paper context) - Write exact JSON to `/app/result.json` with the schema: `{"value": <result>}` - After writing, verify with: `cat /app/result.json` - Do not guess values; if a value cannot be computed, set it to `null` The value can be a number, string, list, or dictionary depending on the task requirements. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
