new 3.6-cm wavelength observations were made using the Very Large Array (VLA) of the National Radio Astronomy Observatory (NRAO)[^2]. These VLA radio continuum observations were carried out in 2006 May 31 and June 08 at the frequency of 8.46 GHz. The array was in the BnA configuration and an effective bandwidth of 100 MHz was used. The absolute amplitude calibrator was 1331+305 (with an adopted flux density of 5.21 Jy), and a source model provided by NRAO was used for its calibration. The phase calibrator was 1626$-$298, with bootstrapped flux densities of 1.684$\pm$0.003 and 1.823$\pm$0.004 Jy for the first and second epochs, respectively. The phase center of the array was $\alpha=16^h58^m17{\rlap.}{^s}202$ and $\delta=-42^\circ52'09{\rlap.}{''}59$ (J2000.0). The data were edited and calibrated using the software package Astronomical Image Processing System (AIPS) of NRAO. To correct for amplitude and phase errors caused by the low elevation of the source, the data were self-calibrated in phase and amplitude. No significant variations were found between the two epochs of observations (separated by only eight days) and the final analysis was made from the result of concatenating all data. The average epoch for the two data sets is 2006.42, which we use in subsequent analysis. Clean
