Detailed analysis of intensity ratios of unsaturated methylidyne (CH) A--Xand B--X bands suggests consistency of the recently published oscillatorstrengths of A$^{2}\Delta$ -- X$^{2}\Pi$ (0, 0) -- 4300 \AA\ andB$^{2}\Sigma^{-}$ -- X$^{2}\Pi$ (0, 0) -- (3878, 3886 and 3890 \AA) bands (ie.506, 107, 320 and 213$\times$10$^{-5}$ respectively). This result is based onextremely high S/N ratio spectra of 45 stars, acquired with threehigh-resolution spectrographs, situated in Chile: ESO LaSilla (HARPS), ESOParanal (UVES) and Las Campanas (MIKE) and MAESTRO instrument situated inNorthern Caucasus (Russia). The calculated methylidyne column densities,obtained using the consistent system of the oscillator strengths toward theobserved targets, are given as well. We verify oscillator strengths of the CH+A-X (0, 0) and (0, 1) bands at 4232 \AA\ and 3957 \AA\ equal to 545 and342$\times$10$^{-5}$ respectively. We also confirm the lack of correlationbetween abundances of neutral CH and CH$^{+}$ which the fact demonstrates thatthey are originated in different environments.
