Dear Dr. Lobzin, dear co-authors,

Thank you for choosing the EGU journal Annales Geophysicae to publish the results of your research. I believe that the DIAS Software, you introduced in the paper, will be a useful tool in the processing and analysis of data provided by the DEMETER satellite.
I am very pleased to say that the article is interesting and well written, nevertheless, as you know, there are some comments and recommendations in the referees reports which need your attention. Thank you for your response to the referees’ comments. Now, please, send us the modified version of the manuscript with indication of all modifications. One of the referees and me will read the manuscript once again.
Kindest regards

Yours cordially

Dear Dr. Lobzin, dear co-authors,
Thank you for sending us a modified version of the manuscript. It has undergone the second revision and I am pleased to say that currently only some technical corrections were suggested (please, see below).
The name of the SW you have designed is „Detection of Ionosphere Anomalies Software” with acronym DIAS. In your reply to the referee’s comments, you stated that at the time of creating the SW, you did not know the European server with the same acronym, which could have happened. You also stated that "But, I think it is possible to remove the acronym" DIAS "from the paper", which was not done in the modified version. In the title, abstract and below in the text, you use the acronym DIAS and add "Software" (DIAS Software), which duplicates the letter "S" in the acronym. From my point of view, I would recommend using the acronym DIA and add the full word "Software" or "SW" for short, then there would be no duplication (e.g. DIA Software) and no confusion with acronym DIAS.
Also one of the referees added some comments to be considered:
Abstract. Correct date. It is not January 10.
-DEMETER the satellite. The VLF band is 0.02-20 kHz.
-Figure 2. The bottom graph. How the coloured bar on the right is connected with the line? The same for Figure 5.
-Figure 7. What are units of Y-axes?
Please, consider the comments above and send us your response and the final version of the manuscript.
Kindest regards

Yours sincerely
