Number of scalar calibration terms

## Specification

Alias: none

Argument(s): INTEGER

## Description

This keyword describes the number of scalar calibration terms. It is meant to be used in conjunction with `field_calibration_terms`, which describes the number of field calibration terms. The total number of calibration terms, both scalar and field, is given by `calibration_terms`. If only scalar calibration terms are specified, it is not necessary to specify the number of scalar terms explicitly: one can simply say `calibration_terms` = 5 and get 5 scalar terms. However, if there are three scalar terms and 2 field terms, then `calibration_terms` = 5 but `scalar_calibration_terms` = 3 and `field_calibration_terms` = 2.

Calibration terms are responses that are used with calibration methods in Dakota, such as least squares optimizers. Currently, each scalar term is added to the total sum-of-squares error function presented to the optimizer. However, each individual field value is added as well. For example, if you have one field calibration term with length 100 (e.g. a time - temperature trace with 100 time points and 100 temperature points), the 100 temperature values will be added to create the overall sum-of-squares error function used in calibration.
