Spectra of all lines integrated over 0.5^′′ × 0.5^′′ region toward the selected positions (Table 2), as indicated in the moment maps of SiO (Fig. 2). Top 3 panels are the spectra in the central part of L483 while bottom 6 panels show those in the SiO blobs and the NE-cloud region. Considering the different flux levels between the central part (upper 3 rows) and others (lower 6 rows), different plotting ranges are employed. Vertical lines indicate the systemic velocity of V_LSR = 5.5 km s⁻¹. Gaussian fitting results are overlaid with thin red curves (Tables C.1–C.3).
