235 MHz $--$ Results

Here, we present the observational results at 235 MHz. The data analysis procedure has been already discussed in the Chapter 3. To continue, the observational results were obtained using several tasks of the data analysis package AIPS. We present the $uv$-distance plots and the radio images of a few of the representative sources.

Details of the observational results are tabulated in the table B.1 in Appendix B. The table includes, (i) the flux density of the source, both, the peak and the integrated, (ii) best angular resolution, (iii) deconvolved size of the major axis of the source, and (iv) the information of the additional field sources, called secondary sources, within the field-of-view, (v) $RMS$ of the map.

A field of $\sim$ $3.5^\circ$ was mapped to look for the presence of secondary sources within the field-of-view because of wide primary beam at low radio frequencies. Since the field-of-view is large and the sky is full of point sources, we often detect many sources within this field-of-view. Therefore, when the secondary source(s) is(/are) present in the field-of-view, we give the following information of the first two brightest secondary sources. (a) flux density, (b) distance from the target source, and (c) its position angle.

The same table also gives the information of the number of other detectable secondary sources (having flux density greater than $\approx$ 5$-$15% of the flux density of the primary source) within the field-of-view. If the source is not detectable within the integration of observed time and if there is no other strong source, apart from the target source at the phase center, a syntax '$-$' has been put in order to indicate the absence of the information regarding the source or the secondary sources.
