# PhotosynQ Glossary
These terms describe the current PhotosynQ Project, application, instrument, and data workflows.
| Term | Definition |
|---|---|
| App | Program that can be installed on a Device. |
| Canopy | A Project-level subscription under which the Project may be discoverable while its measurements remain restricted to authorized Project users. |
| Contribution | Measurements taken for a Project and submitted to PhotosynQ. |
| Device | On PhotosynQ, computers, phones and tablets are generally called Devices. |
| Project Forum | A discussion area available only to authorized members of a Project team. It is not a global public forum. |
| Forum Post | A comment, question, or image shared with the authorized Project team. |
| Forum Thread | A Project forum topic containing related posts. |
| Firmware | The software installed on an Instrument. |
| Device QC | A local pre-collection check of MultispeQ communication, battery, sensors, calibration memory, and tested LED/detector responses using an empty clamp. |
| Field QC | A local collection-readiness workflow that runs the bundled Photosynthesis RIDES 2.1 Protocol on three representative leaves. |
| Flag | Some measurements might be of low quality, so they can be flagged. Flagged data is hidden during analysis but is NOT deleted from the Project. |
| Instrument | Equipment that connects to Apps and are used to take Measurements (e.g. the MultispeQ). |
| Macro | Macros are small pieces of code connected to a Protocol to help in analyzing the measurement right after it is finished. |
| Project | Measurements collected on PhotosynQ are organized and stored in Projects. Users can define Protocols and Project Questions for each Project. |
| Project Administrator | Project Administrators get invited by a Project Lead to help manage the Project and take measurements. |
| Project Collaborator | A Project team member invited by a Project Lead or Administrator, or approved after requesting access, who can take measurements. |
| Data Explorer | The Project web workspace for filtering, visualizing, mapping, inspecting, and exporting measurements. |
| Project Lead | The Project Lead is the person who initially creates a Project. Also, the Project Lead invites Administrators and Collaborators. |
| Project Questions | Answering these Questions before every measurement improves the analysis and documentation of each contribution. |
| Project Subscription | The Vault or Canopy access and billing selection applied to an individual Project. Current terms are shown in Project Settings. |
| Protocol | Protocols are instructions for an Instrument on how to conduct a measurement. |
| Quick Measurement | A local application measurement that is not attached or uploaded to a Project. |
| Series (Data Explorer) | A filtered subset of Project measurements created from Project Questions, users, instruments, dates, or combinations of those fields. |
| Synchronize (or Sync) | Apps need to synchronize with PhotosynQ to provide you up to date Projects, Protocols and Macros. |
| Thresholds (Data Explorer) | Display limits that help inspect a specific parameter range. They do not automatically determine scientific validity. |
| Vault | A Project-level subscription for a Project and measurements restricted to authorized Project users. |
