Abstract
For both above papers, there were mistakes in calculation of the spectral index errors in Tables 3 which have been corrected in the following replacement tables respectively. Therefore the integrated flux density based spectral index error cited in the text changes to $0.34\pm0.25$ (not $0.34\pm0.15$) for HB3, $0.25\pm0.08$ (not $0.25\pm0.03$) for OA184 and $0.36\pm0.10$ (not $0.36\pm0.06$) for VRO42.05.01. The correct beamwidth for the 2695 MHz effelsberg 100-m in Table 4 (for the both papers) and 5 (only for the second paper) is $4.3 \times 4.3$ arcmin not $3.4 \times 3.4$ arcmin. None of the above corrections affect our discussions and conclusions in the two papers.

Table 1: The table will replace the Table 3 of Paper 1. Integrated flux density and spectral index of the whole area and five subareas* of HB3 and of Compact Sources (CSs) at 1420 MHz and 408 MHz.

Table 2: The table will replace the Table 3 of Paper 2. Integrated flux densities and spectral indices of OA184, VRO42.05.01, and compact sources within OA184 and VRO42.05.01.
