Minor Typo in GUI Version — ZTD Plotting #9

Closed Waley04 closed 1 year ago

Waley04 commented 1 year ago

Dear Developers,

I suspect that ZDD in the Y-axis for the upper panel of the ZTD plot is a typo. I think it is ZHD. Please, refer to the following plot:

ztd_2023100_abpo

Note: I observed this in the latest commit.

Thanks with regards,

Waley.

Thank you for your report.

This may be a misunderstanding. The acronym “ZDD” stands for “Zenith Dry Delay” and is used as an alternative name for “ZHD” or “Zenith Hydrostatic Delay.” According to C. Rocken (2001), and etc., these two terms are basically the same.

@PrideLab,

Thank you for providing clarification on the acronyms. I already know about this relationship, however, I was under the impression that ZHD is the commonly used acronym.

I apologize for any inconvenience caused.

Otherwise, I have taken note of this information with kind regards.

Waley.
