Biswajit Paul, Harsha Raichur
In Paul, Raichur and Mukherjee (2005) we had reported a spectral mode change
in the X-ray binary pulsar Cen X-3 using the then available ASM light curves of
Cen X-3. Being mindful of the fact that instrument calibration or other issues
like gain changes, software issues etc. might give rise to some of the
artifacts, we had used the ASM light curves of three other X-ray binary pulsars
namely Her X-1, SMC X-1 and Vela X-1 for comparison for the same observation
times. In light of the recent finding of M\"{u}ller et al. (2011); which
reports the non-detection of such features in the current ASM light curves
available on the HEASARC website and with other instruments like MAXI, SWIFT
and INTEGRAL, we would like to point out the inconsistency between the ASM
ligthcurves available in 2005 and now. This information will be very useful for
other users of ASM light curves.
