Abstract The High Resolution Telescope and Spectrograph (HRTS) instrument has been flown three times on sounding rockets and has dramatically demonstrated the value of high resolution (spectral, spatial, and temporal) coupled with wide spectral and spatial coverage. Through the use of film as a detector, the HRTS can capture a large spectral and spatial range simultaneously. Because of the high spectral and spatial resolution, each exposure contains 10 million data points. After digitizing, this equates to a data collection rate of four megabits per second for a 20 second exposure. Because of the large film format, a set of HRTS exposures has recorded complete profiles of over 2800 emission lines simultaneously at 1000 different locations on the Sun. These emission lines originate in temperature regimes ranging from the temperature minimum to the corona. This allows a statistical analysis of temperature, pressure, density and velocity in many layers of the solar atmosphere.
