Dear Editor and Referee 2,

thank you very much for your Referee's report.

We considered all comments and made appropriate changes, see 
the new version of our manuscript.
We also added and removed some references.
Our answers to the referee's comments follow.

With best regards,

Marian Karlický and Ján Rybák

Our answers to the Referee's comments:

Referee's comment:

1) concerning Figure 2, the author mentioned that normal (reverse) frequency drift were
   found in the 800-2000 MHz (> 2000 MHz) band. Can the author estimate the density
   (and height) of this bifurcation point.

Our answer:

To see better the positive and negative frequency drifts of type III bursts
we added the detailed radio spectrum (now Fig.3), where you can 
see not only drifts of bursts, but also the bifurcation region,
where type III bursts start to drift to higher and lower frequencies.
The mean frequency of this bifurcation region is about 1400 MHz.
Considering plasma emission mechanism of type III bursts,
then for the emission on the fundamental frequency the bifurcation frequency 
corresponds to the plasma density of about 2.4 x 10^10 cm^-3.
On the other hand, for the emission on the harmonic frequency 
the density is 6.0 x 10^9 cm^-3.

Determination of corresponding heights at this frequency range  
and during the flare event, using density models of the solar atmosphere, 
is not very reliable.

Referee's comment:

2) relating to 1), in Figure 8 a carton is shown to illustrate the acceleration process.
   For electrons propagating upward, will they bend and eventually precipitate down to solar
   surface, so that a U-shape type III burst can be found? Does the fact that there is no
   U-shape type III bursts, mean that the rising magnetic rope is by itself an open field
   line?

Our answer:

We did not observe U bursts on lower frequencies. Maybe that the electron beams,
generating type III bursts, escape from the magnetic rope along some open magnetic 
field lines. On the other hand, type III bursts in our case are not broadband.

Referee's comment:
 
3) Labels in multiple figures are too small to read. Please modify figures accordingly.
   In second panels of figure 3 and 4, giving the meaning of the shading.

Our answer:

It was done. We also improved the description of the used method.     

Referee's comment:

4) caption of figure 1, 13:3 should be 13:32. Spelling/grammatical errors at places need to be fixed.

Our answer:
Yes, it was corrected and English was improved.
