Remote measurement data of night-vision markers for a submarine unit of the Navy

Emergency luminous markers are installed inside the submarine and on the uniforms of watch-keeping soldiers. These serve as operational and evacuation guides in the event of a complete loss of electrical lighting.These markers store energy when exposed to light and can continuously self-illuminate for up to 10 hours in darkness. Due to confidentiality requirements, test personnel were unable to conduct onboard random testing of the markers' brightness. Instead, the measurement method involved soldiers carrying instruments to take readings on-site, with data transmitted remotely.The final dataset contains 12 hours of continuous brightness monitoring data for the luminous markers, sampled at approximately one-second intervals. The data was submitted in Excel format.
