[CV] Request new entry: base peak intensity maximum until RT

[julianu]

What is the QC term's name?

base peak intensity maximum until RT

Briefly describe the QC term.

this term is similar to #246 but only takes the BPs into account until a given retention time.
This could maybe be modeled using a tuple or table specifying the RT and the maximum BP until this RT
Also #246 could be modelled using e.g. "-1" as RT to specify "global maximum BP"

What is the QC term's unit?

intensity / arbitrary and time (in seconds)

Value type

MS:4000004 ! n-tuple

Describe any additional information.

This metric is similar to #246 , but can cut away a very high gradient change in the end of an MS run.

A table rather than an n-tuple I think, because n-tuples should contain similar values, whereas tables have different columns (in this case, base peak and retention time maximum). Does it make sense to generalize to an RT interval, e.g. both an RT minimum and maximum? Or to predefine RT intervals, such as in the QuaMeter quartile metrics?
