* The proposal that was discussed was $table_model and the following comments, issues were raised
 
- The syntax proposed in Section 10.9 is not consistent with the rest of reworked BNF - also uses variable as the first argument to the $table_model function when in actuality it can be analog expression for ex: probe.
- Graham is going to take a look at this and will propose a more consistent syntax to what is being proposed.
- The degree_char in the syntax mentiones that it can be 1, 2, or 3 - this is the degree that can be used for extrapolation. There is no specification for degree being "2" in the proposal. It is suggested to create a seperate section for degree explaining what the degree relates to, and create a table similar to the extrapolation table specified in section 10.9.4
- Section 10.9.4 mentions that "spline" can be used as one of the methods for extrapolation. However, its felt that using spline for extrapolation may not be stable. Its safer to have the option as CLAMP or LINEAR when the point falls outside the range specified in the table. Doing a spline extrapolation can lead to erroneous results - error depending on how out-of-range the point is. It was suggested to restrict extrapolation to just linear/clamp.
- Control string is mandatory and an empty control string "" specifies linear extrapolation.
- In general table numbers and figure number are to be added to the document.
 
An updated document shall be sent.
 
regards,
Sri
