Abstract: This is the release of the reduced, reconstructed 3D cubes from the ERIS/SPIFFIER instrument. The Enhanced Resolution Imager and Spectrograph (ERIS) is a general-use infrared integral field spectrograph (IFS) and imager (NIX) that utilises the adaptive optics on the VLT’s Unit Telescope 4 (Yepun). The spectrograph is a medium-resolution IFS that operates in thenear-infrared range of 1 – 2.5 μm (J, H, and K bands). SPIFFIER has twelve grating configurations. Three low-resolution (R~5,000) grating configurations span each of the J, H, and K bands. The nine high-resolution (R~10,000) configurations span each of these bands in sets of three, with each grating spanning approximately one half of the band (one covering the first half, one covering the second half, and one centred on the middle of the band). Three plate scales correspond to an on-sky field-of-view of 0.8" x 0.8", 3.2" x 3.2", and 8" x 8", with corresponding spaxel (spatial pixels) of sizes 12.5 x 25, 50 x 100, and 125 x 250 mas/spaxel, respectively. SPIFFIER can be operated without adaptive optics (AO), with natural guide star AO, and/or with a single laser guide star. The focus of this release is dedicated to the fully reduced data product cubes from the ERIS/SPIFFIER IFS. These data consist of science exposures that have been dark-corrected, flat-fielded, linearity and gain corrected, wavelength calibrated, sky background corrected and, if possible, photometrically calibrated. The reconstructed 3D combined cube constitutes the primary data product and is provided as a multi-extension file (MEF) consisting of the data, error and quality cubes. The fully processed, individual 3D cubes that make up each combined cube are also included, along with the mean collapsed combined cube (white light), the associated sky exposure cube, and the exposure 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.
