11.6 Recap of COS Optional Parameters

---

Most of the parameters to be specified in Phase II are self-evident, such as COS/FUV, or TIME-TAG, the Config and Mode, respectively. Here we provide cross-references to discussions of the various Optional Parameters than can be specified.

BUFFER-TIME

Required with TIME-TAG mode. See Section 5.5.1.

CENTER

Used in ACQ/SEARCH and ACQ/PEAKD. See Section 7.6.2 and Section 7.6.4.

EXTENDED

Indicates an extended source for the data reduction pipeline. Used in TIME-TAG and ACCUM modes. See Section 5.9.

FLASH

Used in TIME-TAG mode only. See Section 5.7.1.

FP-POS

Used in TIME-TAG and ACCUM modes. See Section 5.8.

NUM-POS

Used in ACQ/PEAKD. See Section 7.6.4.

SCAN-SIZE

Used in ACQ/SEARCH. See Section 7.6.2.

SEGMENT

Selects segment A, segment B, or both in the FUV channel. Used in ACQ/SEARCH, ACQ/PEAKXD, and ACQ/PEAKD, as well as TIME-TAG and ACCUM. See Section 5.6.

STEP-SIZE

Used in ACQ/SEARCH and ACQ/PEAKD. See Section 7.6.2 and Section 7.6.4.
