- The range calculation should be reproducible by anyone who has access to the h(t) data:
- The input parameters used to calculate the range should be linked on the page.
- The code used in the calculations should be publicly accessible.
## Actions:
- [X] Switch to method of range calculation using SenseMon type calculation.
- Check against GDS computed range based on GDS-CALIB_STRAIN_CLEAN:
- L1:DMT-SNSC_EFFECTIVE_RANGE_MPC.mean
- H1:DMT-SNSC_EFFECTIVE_RANGE_MPC.mean
- This has been tested in a dev environment and found to show a ~5 Mpc increase in the range. After testing, this was implemented in production during Tuesday maintenance on 06/27/2023.
- [X] Time listed should be in UTC (not local time)
- [X] Y-axis should have automatic mode by default but also have a configurable range.
- It is not possible to set a user-configurable range on the public dashboard. But the y-axis range was changed to an automatic mode so that it will be more zoomed in on the ranges instead of always 0 - 200 Mpc.
- [X] Have written text for the current ranges. - like a text panel that shows the latest range value for each IFO in a way that’s easy to copy. Would be great if there can be a copy button
- This feature was added to production during Tuesday maintenance on 06/27/2023.
- [X] config.yaml: state-vector-on-bits may be out of date, specifically V1. Double-check.
- Confirmed by Nicolas Arnaud.
- [X] calculate range using the reference PSDs.
- This has been done using a script checked into the gwistat repo here: https://git.ligo.org/lscsoft/gwistat/-/blob/master/compute_horizon.py
- command (run on CIT): `singularity exec /cvmfs/singularity.opensciencegrid.org/lscsoft/gstlal:master python3 compute_horizon.py`
- Results:
- H1: 129.18302866211027 (Mpc)
- L1: 147.629978998509 (Mpc)
- K1: 1.3552534451174176 (Mpc)
- V1: 121.4106377103854 (Mpc)
- [ ] update H1 reference PSD after changes were made to the input power and control loops.
- See [original psd](https://ldas-jobs.ligo.caltech.edu/~gwistat/observing/4/a/gwistat/psd.png) compared to [updated psd](https://ldas-jobs.ligo.caltech.edu/~gwistat/observing/4/a/gwistat/H1K1L1V1-REFERENCE_PSD-0-0.png).
- Updated PSD for H1L1 was taken from July 1 00:00:00 UTC - July 7 00:00:00 UTC (KAGRA and V1 unchanged).
- As expected, Hanford's range is decreased slightly but we can see a decrease in the low frequency noise.
- [ ] Investigate FFT length change effect on range (compare 4 vs 8), investigate once sensemon is implemented
