\caption{Time series analysis for those objects in our sample where SiO periods can be established from our data. The SiO variability of GY~Aql, an object considered as a semiregular star at the 
beginning of the survey, shows all the characteristics found in a typical Mira-type star. All 
other objects in our sample were not considered in this analysis because no periodicity 
could be found in the available data.\label{tb:timeseries-results}}
