Dear Authors:

There are a number of minor things I would like the authors to fix before final acceptance. Please correct the MHD system (page 3, line 1). There is the whole term missing; also please make a clear difference between vectors and scalars throughout the manuscript. Please also check the text around the MHD system - there are problems, for example I (unit matrix) and p_t are not used, while identified in the text. This is due to aforementioned mistake. Note that it should be p_t instead of pt. Page 3, line 10: "we do not consider the microscopic interactions"... The ideal equation of state is due to elastic collisions between particles, so assuming an ideal gas law you already assume interaction between particles. Page 3 line 21 - "attributed by the measurement of Avrett..." - this temperature profile was not measured, but inferred from the observed line profiles. Page 5 line 6 - there is "s-2", while it should be s^{-2}. Page 6 Line 2 - the code cannot be "finite volume and finite difference". It can be "finite volume or finite difference", if it is possible to switch that. Page 7 lines 25-30: I still suggest making it properly. I cannot see where in the plot G=255 or 245, because there is no colour bar in this figure. I understand what you are doing there, but ultimately the values, which are shown in the figure, are the values of density. It is the jump of density in the photosphere you see as change in the colour. You do not have to refer to the values of colour to establish the boundary of the simulated jet, you just need to find a threshold value for the density. Page 11 fig. 6 - I do not understand this figure. How do you measure the width of jet at their maximum height, and what is this exactly? Is this width measured when the jet is highest? Then, at which height the width is measured? Or this width is measured at the tip of the jet? Then it is not a reliable measure. If the former, I suggest adding description on where exactly the width is measured. If the latter, then I would suggest to measure the width at half-maximum instead.

Best regards,
your editor.
