Comments: The absorption cross-sections of methyl bromide (CH3Br) are measured between 180 nm and 260 nm at temperatures 
of 295 K, 255 K, 227 K, and 209 K. A parametrical formula is proposed to compute the absorption cross-sections for wavelengths 
between 200 nm and 260 nm and for temperatures between 210 K and 300 K.
