The distribution of the total number of single mid-M and UCD sources with F146 < 21 in the survey fields over 1000 iterations of our simulation, with the scaled space densities shown in blue. This simulation predicts an average of 75,500﹩{}_{-7000}^{+11,800}﹩ single mid-M dwarf and UCD sources in the survey fields (1σ range). Predictions from the Galactic stellar population synthesis models TRILEGAL and Besançon are marked with orange and red vertical lines, respectively (see Section 2.3 for more details).
