We have conducted a comprehensive experimental investigation of the in-plane de Haas van Alphen quantum oscillations in ZrSiS and HfSiS and compared the results to the ab-initio calculations. We found a moderately good agreement for a set of frequencies located between 100 T and 200 T. These could be associated with extremal orbitals of the electron pockets located around the $k_z=\pm\pi/2c$ planes at the edge of the 1st Brillouin zone. In contrast, the experimentally detected low-frequency set of oscillations found around 20 T could not be reproduced by the calculations. Further refinement of the ab-initio calculation has to be conducted to fully capture all the observed features of the Fermi surface in ZrSiS and HfSiS.

Author comments upon resubmission

Dear Referee, Editor,
We are very grateful for your comments and time invested in reading our manuscript, and here we address them.
Some of the suggested questions stated by the referee require additional research and will be addressed in a future manuscript.
A list of corrections and reports to the referee's comments/suggestions has been given in a separated MS Word document.

List of changes

Page 1. Introduction
Two references have been added, referenced added [18] and [24]

Page 5. Results and discussion
“ωc = eB/mc is cyclotron mass" is replaced with "ωc= eB/mc is cyclotron frequency"
“Due to the high sample quality, the oscillations can be detected even at 1 T.” is replaced with "Due to the high sample quality and low effective masses, the oscillations can be detected even at 1 T.”

Fig 2. and Fig 3. The error bars for the effective mass have been added in the figure caption.
