  • On the Photometric Error Calibration for the Differential Light Curves of Point-like Active Galactic Nuclei 
    Goyal, Arti; Mhaskey, Mukul; Gopal-Krishna; Witta, P. J; Stalin, C. S; Sagar, R (Indian Academy of Sciences, 2013-09)
    It is important to quantify the underestimation of rms photometric errors returned by the commonly used APPHOT algorithm in the IRAF software, in the context of differential photometry of point-like AGN, because of the ...
  • Optical variability of radio-intermediate quasars 
    Goyal, Arti; Gopal-Krishna; Joshi, S; Sagar, R; Wiita, Paul J; Anupama, G. C; Sahu, D. K (Blackwell Publishing, 2010-02)
    We report the results of our intensive intranight optical monitoring of eight optically bright `radio-intermediate quasars' (RIQs) having flat or inverted radio spectra. The monitoring was carried out in R band on 25 nights ...
