      Change BAYESTAR low frequency cutoff to 15 Hz · 0eca694f
      Leo Pound Singer authored
      Search pipelines do not report their low frequency cutoffs in a
      uniform, machine readable way in the coinc.xml files. BAYESTAR has
      been using a default value of 30 Hz. A mismatch in low frequency cutoff
      will lead to a systematic bias in luminosity distance.
      
      In O3, search pipelines used the following low frequency cutoffs:
      
      | Pipeline                              | Cutoff                         |
      | ------------------------------------- | ------------------------------ |
      | gstlal (full bandwidth, stellar mass) | 15 Hz                          |
      | gstlal (full bandwidth, IMBH)         | 10 Hz                          |
      | gstlal (early warning)                | 10 Hz                          |
      | SPIIR                                 | 15 Hz                          |
      | PyCBC                                 | 18-30 Hz depending on template |
      | MBTA (BNS)                            | 25 Hz                          |
      | MBTA (NSBH)                           | 23 Hz                          |
      | MBTA (BBH)                            | 21 Hz                          |
      
      15 Hz is a compromise value that is closer to what the pipelines
      actually use. A complete solution would be to add an `f_lower`
      column to the `sngl_inspiral` table so that pipelines can report
      their low frequency cutoffs.
