Prediction for possible detection of ²⁶Al-decay γ-ray as seen by the future COSI γ-ray detection mission. The x - and y - axis represent the viewing angles of the future instrument. Note: the color-coding here is opposite to that in Figs. 1 and 2 (to achieve a similar color-coding as in Kretschmer et al. 2013), so that higher intensity is represented by darker colors and no detection is represented by the white background. The pixels are Kaiser-interpolated to account for a possible neighbour dependence, as in INTEGRAL/SPI.
