Can we check the calculation of dating duration on the Edges tab #13

Open Keith-May opened 2 years ago

Keith-May commented 2 years ago

example of c1041 > c 1024 1041 dates(28) 200 - 300 1024 dates(26) 120 - 160 Edge corresponds 161 - 199 (i.e. gap between 160 - 200) 160 is the TPQ for c1024 but 200 is not necessarily the start for c1041 - should we use TPQ1041 = 300 and edge duration then becomes: minimum 160 - 300 = 140

So just to clarify:

  1. edge bounds should use derived years of contexts (as example edge starting at 160 not 161).
  2. edge min year will be same as derived max year of source context.
  3. edge max year will be same as derived max year of target context.

  1. "edge bounds should use derived years of contexts (as example edge starting at 160 not 161)". - YES but only if that best reflects the "Meets in time" ATR in our 1yr accurate timescale. So the "start" date of the edge should reflect that it "meets in time" with the end date of the preceding context.

  1. edge min year will be same as derived max year of source context. YES, but see suggestion below
  2. edge max year will be same as derived max year of target context. YES I think it would be helpful (at least to me) to explicitly show the Edge dating in the stratigraphy tab? Rather than just the min & max durations. Currently, especially since changing the label to "stratigraphy", there is a mix of data showing and it is not obvious what the min & max durations are referring to unless you already know. I suggest the table on the stratigraphy tab has new headings
    "Edge start date" : min duration : "Edge End Date" : max duration :

I think we may need an alert colour system for this data too, in the stratigraphy tab? So if the result of the calculated edge results in a negative duration we flag it with an Amber (orange) colour (possibly even a Red? - TBC). This may also help in cases such as the XSM10-c1019 example where 1019 (within Phase 6) is above c1024 which is in a separate Phase (P5.02) and below 1033 which is also in a separate Phase (P7)

It is noticeable that context 1019 (which has a -90 min duration in the stratigraphy tab) also has an Orange highlight in the Contexts tab. I think it may be a discussion topic for the May 4th Workshop around how people might find the Edge duration data useful, as it is a new idea? image
