ALMA is releasing data acquired as part of the Extension and Optimisation of Capabilities effort (EOC). These data were taken as part of the High-Frequency Long-Baseline Campaign (HF-LBC-2021) during Cycle 7, which was organised to test the calibration and imaging capability of ALMA at high-frequencies (397 - 908 GHz, Band 8-10) and using long baselines (~16 km). One main priority was to make a final validation of the band-to-band (B2B) phase referencing observation mode in Bands 8, 9, and 10. This technique allows the calibration of high-frequency observations by using a phase calibrator observed at a lower frequency, e.g. pairing Band 10 target observations with a Band 7 phase calibrator. The campaign conducted validation tests observing a complex structure (non-point-source) target source, R Lep, a carbon-rich evolved star in Bands 8, 9, and 10. Details of the campaign is detailed by Asaki et al (2023 Aug ApJ accepted). The successful campaign helped lead to the opening of Bands 8-10 long-baselines during Cycle 9. R Lep in Bands 8, 9, and 10 are available for download.
