Table~3 contains the results of our \bvr\ha\ $+$\nii\ photometry. The descriptions of the items in the table are as follows. \\ (1) ID : \hii region numbers as identified on the accompanying charts (Figs~1--8). \\ (2)--(3) X, Y : The X and Y pixel coordinates on the aligned CCD images, which are the same as that appearing on the grid around identification charts. For \ngc 4449 the grids contain different pixel numbers than that given in these columns for the reasons mentioned in the previous subsection.\\ (4)--(5) RA, DEC : Approximate position of the \hii region, along Right ascension and declination in seconds of arc, with respect to the galactic nucleus. These were obtained by transforming X and Y assuming that the RA-DEC axis is aligned with X-Y axis of the CCD. Since the alignment during observations is only approximate ($\leq 5$\degr ), RA and DEC values away from the center are less accurate, compared to those near the center of the CCD. Thus the positions should be used only for identification purposes. E, W, N, and S preceeding the numbers indicate respectively whether the \hii region is to the east, west, north or south of the nucleus of the galaxy. \\ (6) DIA : Diameter of the aperture chosen for magnitude extractions in seconds of arc. \\ (7)--(9) $ V, B-V, V-R$ : $V$ Magnitude, $B-V$ and $V-R$ colors of \hii regions after subtracting assumed background. The rms errors on the measured magnitudes are in the range 0.05--0.10, as estimated from measurements on multiple frames.\\ (10) $\log F\alpha$ : Logarithm of the observed \ha\ $+$ \nii\ flux in units of \ergscm. The values are accurate to 0.1~dex. \\ (11) W(\ha) : \ha\ $+$ \nii\ emission equivalent width in \AA\ with $R$ magnitude as an estimate for the continuum at \ha. Following equation is used in the computations. $$W({\rm H}\alpha)({\rm \AA}) = {F_\alpha \over 10^{-0.4(R+48.6+\kappa_r)} } \left( {\lambda^2 \over c} \right) \ = { F_\alpha \left({\rm {erg~s}}^{-1}{\rm {~cm}}^{-2}\right) \times 1.633\times 10^{-11} \over 10^{-0.4(R+48.6)}} \\ $$ where $\lambda$ and $\kappa_r$ are the effective wavelength and zeropoint for $R$ band (Bessell 1990). The measurement errors are $\leq 20$\,\AA. $R$ band magnitudes used in the above definition include emission from the nebular continuum and lines. \\ (12) Qual. : An index of photometric quality. See the discussion below for definition. \\ (13) Other Id. : Identification from other authors when available. Notes to the table, list relevent references. For measurements with bigger apertures, individual GEHRs enclosed within the aperture are indicated. \\ The values in the catalogue are given a photometric quality index based on the errors on the derived $B-V$ and $V-R$ colors due to the uncertainty in the background estimation, following the methods discussed in the Appendix. Errors on \bvr\ magnitudes are computed using Eqn.~7 of Appendix assuming $x=1.1$. The photometric quality is 1 if the computed errors on $B-V$ and $V-R$ is $\leq 0.1$ mag. Similarly regions having errors between 0.1--0.2 are given an index 2, those between 0.2--0.3 are given an index 3. Index 4 means that the estimated errors in one of the colors is greater than 0.3 mag. It should be noted that the photometric quality index is only a measure of the background domination and is not actual error on colors. Higher the index, more sensitive are the colors to the background measurement. As can be seen from Table~2 (column 7), correction for this uncertainty has the effect of making the colors systematically bluer than the catalogue values. The actual errors on the colors and magnitudes are less than this because a part the underestimated backgrounds might well be compensated by weak emissions from the extended halos outside the chosen apertures.
