| 6485.html | 2017-02-14 11:23 | In addition to adding hardware for the bullseye QPD test to measure beam size changes coming out of the HPO, we need to make some software changes in Beckhoff so that we can use a spare whitening chassis. | 34152 34154 |

| 6482.html | 2017-02-13 13:29 | Gil Hibbs from Hibbs Engineering will be onsite Tues. Feb. 14th at 1:30 pm to look at MX or MY to scope out cryopump bake enclosure design in preparation for cryopump decommissioning post O2. | |
| 6481.html | 2017-02-13 13:08 | Interferometer studies when LLO is down. This will include injections to attempt to distinguish between scattering and clipping at the ITM elliptical baffles, adjusting IMC_WFS offsets, injection to study scattering at ERMY and X, noise measurements immediately after A to L, and diagnostic injections if scattering becomes evident. | |
| 6480.html | 2017-02-13 13:00 | Update GDS to gds-2.17.13-1 on the DMT. As per, https://bugs.ligo.org/redmine/issues/5110 John Z. says the changes are: The new version (gds-2.17.13-1) contains a bunch of infrastructure tweaks that have been well tested offline. These include: * correct tagging of dataValid when reading data segments that are shorter than the length of a frame * interleaved reading of data from multiple online frame streams, i.e. if there are two online data streams providing input data to a monitor, the data are read from both streams as they arrive rather than reading data from one stream first, followed by data from the second stream. The main reason that I would like to install the package now is that it includes the shared memory partition multiplexer. This will be necessary for implementing the dual broadcaster configuration and I would like to have this package installed and running before switching to a dual-broadcaster configuration, hopefully next Tuesday while I am ad LLO. | 34152 |
| 6479.html | 2017-02-13 12:54 | Update gstlal-calibration on the DMT to gstlal-calibration-1.1.4-v1 and restart it. As per, https://bugs.ligo.org/redmine/issues/5115 the changes are: * The NOGATE channels for the calibration factors (kappas) have incorrectly computed values when the kappas are gated. (This does not affect the applied values.) * The kappas are being gated by the observation-ready bit of the ODC state vector, corrupting the data during broadband injections. The calibration team holds that gating with the coherence of the calibration lines is sufficient, and the state vector gating is unnecessary and detrimental. * The pipeline exits on bad dataValid flags, a feature that Greg Mendell would like removed for C01 production. The new version will fill in those time with zeros and mark the data as bad via the h(t)-ok bit of the calib_state_vector. * Removal of all audiorate and lal_reblock elements. These are no longer necessary to clean up the data, since this is all done at the beginning of the pipeline by an element called lal_insertgap. Removal of these redundant elements is expected to reduce CPU usage. * Rearrangement of queues in the pipeline. This is aimed at the eventual goal of reducing the latency of pipeline from ~10 seconds to ~1-2 seconds, but is not currently expected to have any noticeable effect. | 34126 34152 |
