SOLAR/SOLSPEC combines three absolutely calibrated double monochromators with concave gratings for measuring the solar spectral irradiance (SSI) from 166nm to 3088nm. This physical quantity is a key input for studies of climatology, planetary atmospheres, and solar physics. A general description of the instrument is given, including in-flight operations and performance of the ultraviolet (UV) channel from 175nm to 340nm. We developed a range of processing and correction methods, which are described in detail. For example, methods for correcting thermal behavior effects, instrument linearity, and especially the accuracy of the wavelength and absolute radiometric scales have been validated by modeling the standard uncertainties. The deliverable is a quiet Sun UV reference solar spectrum as measured by SOLAR/SOLSPEC during the minimum of solar activity prior to cycle 24. Comparisons with other instruments measuring SSI are also presented. Description: This file provides the data of the Figure 12 of the paper. It is the average spectral irradiance of the Sun as measured by the space instrument SOLAR/SOLSPEC on ISS during the minimum of solar activity prior to cycle 24. Spectral range: 175nm-340nm by step of 0.5nm. Time interval for averaging: 6th June 2008 - 26th April 2009. File Summary:
