<p style="margin-top:0;margin-bottom:0">I'm still waiting for comments for the timing paper. If you have any comments on the paper, can you let me know so I know whom I should expect reply from? If possible can you send me your comments within 2 weeks from
now?</p>

<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">I have completed a draft of my LOTAAS timing paper which includes the first binary pulsar discovered by LOTAAS and 20 other sources. In the paper, I have provided timing solutions, multi-frequency observations to study
profile evolution and to measure spectral indices. There are also separate sub-sections for the binary pulsar and J1657+3304 which shows flux density variation of a factor of 10 over 300 days.</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">One notable issue I have now is to explain why did our sensitivity not improve as much as expected when we correct for the pointing positions towards the pulsars from follow-up positions to timing positions. The worry
here is the systemic errors we get for not accounting for the less than expected sensitivity. Currently I used the measured flux densities as it is if the change in positions is less than 1 arcmin and only use the observations with corrected positions for
changes that are more than 1.5 arcmin (There are no pulsars with offsets between 1 and 1.5 arcmin).</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">Anyways, let me know if you have any comments on any aspects of the paper.</p>
