NIRSPEC Search for Gaseous Plumes from Europa
This dataset contains NIRSPEC spectra of Europa taken over 18 nights between 3 Feb 2016 and 7 May 2017. Most observations are with the KL filter (2.1-4.2 microns); only the night of 15 March 2017 is with the M-wide filter (4.4-5.5 microns). Observing logsheets, raw data ("Level 0"), and reduced data ("Level 1") are available for each night and for each orientation of the slit on Europa. The reduction and flux calibration of the data are described in the Methods section of Paganini et al. (2020).
This work was supported by a NASA Key Strategic Mission Support (KSMS) Keck PI Data Award (PI: L. Paganini), administered by the NASA Exoplanet Science Institute.
