[Pansophy] VTRF traveler issue

Hi Pansophy Team,

There is some issue with the "Excel spreadsheet template for VTA RF measurements" (page 0) in the traveler "L2PRD-CAV-VTRF  Rev: R4 (LCLSII (Production Cryomodule) Vertical cavity Testing, currently in use)". Looks like when the travler was updated last time, the link rolled back to an earlier version of the spreadsheet.

Critical issues about the spreadsheet:
1) It is not the latest version, to my knowledge the latest version should be "27Sept2018" version. It generates incomplete file name and the horizontal error bars in the Q0-Eacc plot are wrong, but these could be manually adjusted with more time.
2) The "Copy Workbook without Macros" function does not work properly, depending on which version of the spreadsheet, it may generate a blank file with/without an error message. The tester either need to save the file with Macro in it or somehow find a version that has this function working properly.

I have the latest spreadsheet saved on my desktop to use, but not all people using the traveler know these issues.

In addition, the link to "LCLSII VTA RF Testing Procedure" is missing. Here is the link to the latest version:

Thanks,
Liang
