**spectro/average**

### Summary

Average or merge two or more .ti3
measurement files.

If only one input file is provided, all the patches with the same
device values will be average together.

### Usage

usage: average [-options]
input1.ti3 input2.ti3 ... output.ti3

-v
Verbose

-e
Median rather than average

` -g
Geometric Median of PCS in encoded space`

` -L
Geometric Median of PCS in L*a*b* space`

` -X
Geometric Median of PCS in XYZ space`

-m
Merge
rather than average

input1.ti3
First
input file

input2.ti3
Second
input file

...
etc.

output.ti3
Resulting
averaged or merged output file

All keywords and other table data will be taken from the first input
file. By default the input files are averaged, but they can be
merged by using the -m
flag.

The fields must be the same and in the same order. For averaging,
the device values must be the same and in the same order.

If the **-e** option is used, then the independent median (i.e.
Marginal median) of the field values is used, rather than the
average.

If the** ****-g** option is used, then Geometric
Median of PCS values is computed in their encoded space (i.e.
XYZ or L*a*b*).

If the **-L** option is used, then Geometric Median of PCS
values is computed in L*a*b* space.

If the **-X** option is used, then Geometric Median of PCS
values is computed in XYZ space.
