Context.The investigations of the photometric and spectral variability of Pre Main Sequence(PMS) stars are essential to a better understanding of the early phases of stellar evolution because this critical early stage of star determines its mass and path of evolution.Especially V2493 Cyg is a special type of star that only few numbers of stars have...

... veiling correction was done for lines that are in absorption; hence, these accretion rate estimates can be slight under estimates. Figure 12 shows all the estimates of accretion rates from various lines as a function of their wavelengths. Figure 13 shows the normalized accretion rates obtained from different lines at different Julian Date. ...
