All Tables

Table 1: Properties of sample stars.
Table 2: Seeing-corrected 7-mm flux densities, spatial resolutions, and estimated source sizes. The stated uncertainties for the flux densities do not contain the uncertainty of the absolute flux calibration.
Table 3: Summary of centimetre observations. 1.3-cm values corrected for seeing-related flux reduction. The uncertainty in the absolute flux density calibration is not included.
Table 4: Spectral slopes derived from power-law fitting in the range 1-7 mm using literature values (Table 5) and our 7-mm data (Col. 2). For objects without centimetre measurements, a 20% contribution of free-free emission was assumed (denoted by brackets in Col. 3). Spectral slopes corrected for free-free radiation are listed in Col. 4. The estimated dust opacity indices $\beta ^{\sim }$ (Col. 5) were corrected for optically depth (using $\Delta =0.2$ ), yielding the final $\beta$ values (Col. 6).
Table 5: Millimetre measurements and IRAS photometry compiled from the literature. The columns $\theta _{\rm B}$ list the HPBW; note that the IRAS PSF sizes are given in arcmin.
