I am attempting to read the most recent historian entries for some tags in a remote historian without any interpolation. Basically the current value of the tag according to the historian. There was a similar post previously that went unanswered ([LINK](https://forum.inductiveautomation.com/t/querying-tag-history-by-quantity-not-time-range-with-scripting/34627)).

I’ve tried playing around with both the queryTagCalculations and queryTagHistory with mixed results. queryTagHistory seems to interpolate and queryTagCalculations sometimes returns no values for unknown reasons.

```auto
system.tag.queryTagCalculations(paths=pathList, calculations=["LastValue"], startDate=startTime, endDate=endTime, noInterpolation = True)

system.tag.queryTagHistory(paths=pathList, startDate=startTime, endDate=endTime, returnSize=1, aggregationMode="LastValue", returnFormat='Tall')

```
