Data Model: oow.I

General Description
The oow.I files contain exposure level inverse variance weights for the ooi.I injection image files. These differ from the oow files for the extension undergoing injection because the flux from the new sources must be incorporated into the calculation of the weights.
Naming Convention
c4d_[0-9]{6}_[0-9]{6}_oow_[grizY]_v1\.I\.fits\.fz, where the numeric label corresponds to a rough exposure date-time, "oow" indicates this is a weights file, the band observed is indicated (grizY), a version number for the NOIRLab community pipeline which performs image preprocessing is appended, and the "I" indicates that a synthetic injection has occured. This naming convention follows the convention set by NOIRLab.

Sections

HDU0: PRIMARY

Exposure level header containing meta information about the telescope, pointing, etc. For more details, see the NOIRLab (formerly NOAO) documentation. Identical to oow file header.

HDU1: N7I

Weights from the injected version of the CCD specified by the HDU name. Header contains CCD level information from the telescope. Identical to oow file header.
