Normalised column densities of N–H (a), C–H (b), and C=O (c) are represented by filled black circles for amorphous NH₂CHO on amorphous silicates at 16 K, as the UV photon fluence increases. These values are normalised using the corresponding initial column densities. The error arising due to baseline subtraction was taken into account in the error estimation. When the error bar is not visible, it indicates that the error is within the size of the filled circle. Additionally, the best fit of Eq. (1) to the data is depicted with solid red lines. The estimated destruction cross-section (σ_d) and the asymptotic destruction (a₁) are also provided.
