IRIS2

The four EXTENDED_n x m recipes cope with missing offset information and a lower completeness (0.25 from 0.4) for automatic registration, thus a smaller fraction of detected objects need match.

ARRAY_TESTS logs to a different location /inst2_soft/iris2red/logs/array_tests.log at the AAT compared with UFTI at UKIRT. References to NDSTARE are not applicable, and so are absent from the documentation. The observation mode is DRM. The upper limit on the readout noise is 20 electrons compared with 30 electrons for UFTI.

There are JITTER_SELF_FLAT variants with a higher registration completeness (0.5 from 0.4) giving purer registration but may rely on the telescope offsets more often.
