Predstavleny rezul'taty obrabotki dannykh nablyudenii metanol'nogo mazera I klassa DR21(OH) na radioteleskope VLA na chastote 44 GGts. Nablyudeniya provodilis' v 2003 g., dannye vzyaty iz arkhiva NRAO (SShA). Pokazano, chto mazer imeet 18 prostranstvennykh komponentov, 17 iz kotorykh sosredotocheny v dvukh skopleniyakh, a odin etim skopleniyam ne prinadlezhit. V obshchikh chertakh poluchennaya prostranstvennaya struktura sovpadaet s nablyudavsheisya ranee drugimi avtorami, a imeyushchiesya razlichiya neznachitel'ny i ne pozvolyayut opredelit' sobstvennye dvizheniya komponentov, kotorye ne obnaruzheny v predelakh oshibok izmerenii za period 8 let otnositel'no 1995 g.
