Format definitions

Boldface type indicates the name of an APT parameter or a value for a parameter.

(red star) Black text indicates an important note.

Magenta text indicates available but unsupported parameters (requires prior approval from STScI).

Red text indicates restricted parameters (for STScI use only).

Brown text indicates text file parameters.

Items in brackets - <value> - are required values.

Items in square brackets - [<value>] - are optional.

Introduction

Only a subset of possible combinations of spectral elements are permitted. In the following tables, an "S" indicates combinations that are supported.

Combinations marked with an "A" are Available-but-Unsupported. Combinations marked with an "I" (Internal) indicate filters for DARK or BIAS images.
