Hi everyone, I come from a completely different academic background (economics) and with a different purpose than probably any other post. I am trying to feed the LIGO-Virgo-KAGRA logbook entries into an economic model of team performance and I was wondering if someone here (even remotely) knows how projects are organized and whether there is some metric of task completion or failure. After reading the guidelines I still really don’t know if there is a place in this forum for a post like this, so I apologise in advance if this is not the case. Kind regards, ---

Hi, Could you provide detailed information of what you are calling “logbooks”. Given the extent of the collaborations and projects, this could point to several places, some of which might be relevant to your question, and others not. URLs (links to the notebooks in question that you are using would be most helpful) Best Regards ---

Hello, Thank you very much for your answer! An example is the VIRGO logbook: [https://logbook.virgo-gw.eu/virgo/](https://logbook.virgo-gw.eu/virgo/) A list of all the logbooks I am referring to can be found in: [https://alog.ligo-wa.caltech.edu/aLOG/index.php?content=20](https://alog.ligo-wa.caltech.edu/aLOG/index.php?content=20) These contain reports about e.g. runs and commissioning of the gravitational-wave detectors of the different organisations. Best, ---

Hi, The links helped me understand what you were referring to - thanks! I’m not an expert and haven’t used this system for many years, bu the closest thing to organization of the information captured is in the top colored bar (the bar above the author and date and time bar). There are likely many hundreds of possibilities for the labels used here across all the different observatories (LIGO’s LHO/LLO, Virgo and KAGRA), plus all the many subsystems. I suspect that you could scrub these out of the logs and bin them up into a histogram and get a pretty good idea of what the majority of use cases are and frequency, but I’m not aware of any concise tabulation of these and suspect that they can change as modifications are needed to the instruments. As a bit of background, these logs are meant for teams that may be working on the same “aspect” of the instrument to have a way to recognize what activies have been performed. While these logs are publicly accessible the authors are focusing on a target audience of sophisticated colleagues and encouraged to use acronyms well know by colleagues. The goal is to be informative to the future with a reasonable success using the search feature. It is often common to have a summary for each activity which may have some redundancy with prior entries. I’m afraid this is about the extent of my knowledge on the logs. PS. I found a list of acronyms with brief descriptions from 2012, which are dated, but should give you some ideas: 40m Lab R&D/Test Facility at LIGO/Caltech AC Alternating Current ADC Analog to Digital Converter ADCU Analog Data Collection Unit AL Advanced LIGO AM Amplitude Modulation AOS Auxiliary Optics System (subsystem in AL) API Application Programmer’s Interface ASC Alignment Sensing / Control (detector subsystem) ATM Asynchronous Transfer Module BS Beamsplitter (optical component) BSC BeamSplitter Chamber (large vacuum chamber) BPCU Beam Pointing Control Unit BT Beam Tube BTE Beam Tube Enclosure CA Channel Access (EPICS Control & Monitoring system network protocol) CC Civil Construction CDS Control and Data System (detector subsystem) CIT California Institute of Technology CMS Control and Monitoring System (a part of CDS) COC Core Optics Components (detector subsystem) COS Core Optics Support (detector subsystem) CP Chiller Pad (part of FAC) CP Compensation Plate (optical element part of TCS) DAQS Data Acquisition System DC Direct Current (steady state - low frequency) DCC Document Control Center DCU Data Collection Unit DET Detector system DIA Data Information Area (of reflected memory) DMA Direct Memory Access DRD Design Requirements Document EDCU EPICS Data Collection Unit EDSU EPICS Data Server Unit EMC Electro-Magnetic Compatibility EMI Electro-Magnetic Interference EOM Electro-Optic Modulator (optical hardware) EPICS Experimental Physics and Industrial Control System ETM End Test Mass (optical component) FAC Facilities (part of CC) FCMS Facility Control and Monitoring System FCR Facility Control Room FFT Fast Fourier Transform FI Faraday Isolator (optical component) FIFO First In First Out FM Frequency Modulation FM Fold Mirror FR Faraday Rotator (optical component) GDS Global Diagnostic System GPS Global Positioning System GUI Graphical User Interface GW Gravitational Wave HAM Horizontal Access Module HVAC Heating Ventilation and Air Conditioning HWCI Hardware Configuration Item HWP Half-Wave Plate (optical hardware) Hz Hertz ICD Interface Control Document IFO Interferometer IL Initial LIGO INS Installation I/O Input/Output IOO Input Optics (detector subsystem, formerly named Input / Output Optics) IP Internet Protocol ISR Interrupt Service Routine ITM Input Test Mass (optical component) IXS Information eXchange Services LA Louisiana LASTI LIGO Advanced Systems Test Interferometer (test facility at LIGO/MIT) LDAS LIGO Data Analysis System LHAM Horizontal Access Module at Louisiana Site LHO LIGO Hanford Observatory LIGO Laser Interferometer Gravitational-Wave Observatory LLO LIGO Livingston Observatory LSC Length Sensing / Control (detector subsystem) LOS Large Optic Suspension LVEA Laser and Vacuum Equipment Area (of the LIGO observatories) MAP Memory Allocation Pointer (reflected memory) MC Mode Cleaner MCM Mode Cleaner Mirror MIT Massachusetts Institute of Technology MMT IFO Mode Matching Telescope MSR Mass Storage Room MTBF Mean Time Between Failures Advanced LIGO LIGO-E010613-v2 9 MTTR Mean Time To Repair MZ Mach-Zender Interferometer NDS Network Data Server Nd:YAG Neodynium doped Yttrium Aluminum Garnet (laser gain medium) OSB Operations Support Building PDD Preliminary Design Document PDH Pound-Drever-Hall (reflection locking technique) PEM Physics Environment Monitoring PM Phase Modulation POSIX Portable Operating System Interface (IEEE Standard 1003.1) PSL Pre-Stabilized Laser (detector subsystem) PZT Piezo-electric Transducer (mechanical hardware) RAID Removable Array of Independent Drives RAM Random Access Memory RC Radius of Curvature of a Reflective Mirror RF Radio Frequency RM Recycling Mirror SAH Sensor Actuator Heads SCSI Small Computer Standard Interface SEI Seismic Isolation SOS Small Optic Suspension SRD Science Requirements Document SRS Software Requirement Specification SUP Support Equipment SUS Suspension Subsystem (sometimes also Suspension assembly) SYS Detector Systems Engineering TBD To Be Determined (or To Be Done) TCP Transport Control Protocol TCS Thermal Compensation System TGG Terbium-Gallium-Garnet (optical material used in Faraday Isolators) TFP Thin Film Polarizer (optical hardware) TNI Thermal Noise Interferometer (R&D/Test interferometer at LIGO/Caltech) UDP User Datagram Protocol UF University of Florida VE Vacuum Equipment VEA Vacuum Equipment Area VME Versa Module Eurocard WA Washington WFS Wave Front Sensors ---

Dear jkentb, I am very grateful for your time. I was hoping to find some hint in the logs about project completion or failure. The list of acronyms did help to understand the context of the comments. It is already very insightful to know why are these logbooks there and how do researchers actually use them. Now I will be choosing an alternative research avenue but taking these insights with me. Thank you! Best,
