I am proofreading a document and the following sentence came up:
Unless the data is appended only, then we can assume the temporal sampling has changed.
What the writer is trying to say, is essentially the following:
Unless the modification made to the data only included appending new data, then we can assume that the temporal sampling has changed.
Is there a verb that I could use to describe the original data set only having data appended to it?
Something along the lines of:
Unless the data is only (suffixed, verb to describe adding data, ???)
The way it was written sounds as though the original data was appended to something else.
I hope that the question is clear. If possible I'd prefer a single word, however the most important thing is that the sentence is clear, so if need be I will simply rephrase it.
