Abstract: This is the release of the reduced imaging data products from the ERIS/NIX instrument. The Enhanced Resolution Imager and Spectrograph (ERIS) is a general-use infrared imager (NIX) and integral field spectrograph (SPIFFIER) that utilises the adaptive optics on the VLT’s Unit Telescope 4 (Yepun). NIX operates in the near-infrared range of 1 – 5 μm (J to Mp bands) and is designed to provide diffraction limited imaging. The focus of this release is dedicated to the fully reduced products from the ERIS/NIX imager with the 13 or 27mas/pixel cameras (field-of-view of 27”x27” and 55”x55”). The other modes and data formats offered by NIX, coronagraphy, very short exposure “burst” mode cubes, and long-slit spectroscopy are currently not included in this release, but may be added at a later date. The NIX data consists of science exposures that have been dark-corrected, flat-fielded, linearity and gain corrected, sky background corrected, and astrometrically and photometrically calibrated. The data consists of combined (stacked) and resampled exposures, their associated single-band source detection catalogues, and the individual exposures that make up the stacked images. The imaging data are provided as a multi-extension FITS files that consist of the image data, its associated error map, its data quality map, a confidence map, the background map, the error in the background, and the background confidence map. This release is an open stream release, it is complete from the begin of operations, 2023-04-01 (period 111), until present.
Other: This is a dynamic dataset; it is growing as new data is added. The DOI refers to the newest available dataset.
