All the data were taken in a relatively short period of 65 days, which allows a comparative study of the 28SiO maser lines intensities and profiles. The observed differences concerning intensity and line shape among the different maser lines suggest that infrared overlaps deeply affect the pumping of some SiO masers. We qualitatively discuss this effect with consideration to the IR overlaps at 8 µm between the various SiO isotopomers and between 28SiO and water vapor Objects: ---------------------------------------------------------- RA (2000) DE Designation(s) ---------------------------------------------------------- 01 06 25.9 +12 35 53 IRC +10011 = WX Psc 02 22 51.7 +58 35 12 S Per = HD 14528 03 53 28.5 +11 24 20 IK Tau 05 00 54 +56 11 18 TX Cam 05 11 19.4 +52 52 34 IRC+ 50137 = NV Aur 09 47 33.4 +11 25 46 R Leo = HD 84748 = HR 3882 19 06 22.1 +08 13 51 R Aql = HD 177940 = HR 7243 19 57 36.2 -01 53 11 RR Aql = HD 188915 20 46 25.6 +40 06 56 NML Cyg = V1489 Cyg 21 09 32.2 +68 29 28 T Cep = HD 202012 = HR 8113 21 43 30.3 +58 46 48 mu Cep = HD 206936 = HR 8316 23 58 24.3 +51 23 18 R Cas = HD 224490 = HR 9066 ---------------------------------------------------------- File Summary:
