Update spread-sheets of 3D structure

[stefankneifel]

Include changes/modifications discussed at the last scattering meeting (17/May/2018). Please all: revise the spreadsheet and comment!

Spread-sheet is updated according to our discussion yesterday (3D structure and meta-data). @rhoneyager @DaveOri @eec3 please revise, thanks!

[stefankneifel]

@rhoneyager : I just saw, that the spread-sheet one can find on the homepage is not automatically sync-ed with google...

@stefankneifel On Google drive, I can see three copies of structure_scattering_datasets.xlsx.xlsx, last modified Nov. 13, Aug. 16 and Aug. 2. Did you make another copy somewhere?

[rhoneyager]

Okay, I switched the site to use your version.

Two things:

1. For particle_scattering_element_coordinates, did the meeting discuss changing the dimensions from "particle_scattering_element_number, 3, constituent_id" to "particle_scattering_element_number, 3"?

2. particle_constituent_number/constituent_id/particle_constituent_id should also be a local dimension, with a consistent name.

Hello Ryan,

1. For particle_scattering_element_coordinates, did the meeting discuss changing the dimensions from "particle_scattering_element_number, 3, constituent_id" to "particle_scattering_element_number, 3"?

I cannot remember if we discussed this during the last Skype, but will "particle_scattering_element_number, 3" work? How would we handle particles with multiple constituents such as liquid and ice water? Seems to me that "particle_scattering_element_number, 3, constituent_id" would work best in this regard.

2. particle_constituent_number/constituent_id/particle_constituent_id should also be a local dimension, with a consistent name.

I like "particle_constituent_number" as a single number for the number of constituents. For our database it will always be one. And I like particle_constituent_id(particle_constituent_number) as the dimension to hold the individual constituent IDs. My two cents. Eugene

For 1: We already have a separate variable for that: particle_scattering_element_composition. The coordinates variable basically reads as "the nth scattering element is centered at (X,Y,Z)", while the composition variable says "the nth scattering element is (70% ice, 30% water)".

At least, that is how I am interpreting the variables based on the description and comments columns.

Ryan, This all works for me and brings back memories of prior discussions from a long, long time ago. :*) Eugene
