- Description:
- The ESO Science Archive Catalog contains a log of observations performed with the ESO telescopes. Currently available in the observation log are the data from the VLT, NTT, MPG/ESO 2.2m, and the ESO 3.6m telescopes. The observations themselves are stored in an off-line archive and have a proprietary period of one year. After this period the archival data sets are available to the general astronomical community of the ESO member states and Chile.

- Description:
- The EXOSAT Observation Log lists archival information on 2108 pointed observations made with the EXOSAT between May 1983 and April 1986. Data listed include start and stop times, instrumental pointings, object names, proposal identifications, principal investigator codes, and observing instruments and modes of observation. The log is intended as a reference to the data collected during the EXOSAT mission and provides the summary information necessary to determine what observations, if any, may be of interest in an investigation.

- Description:
- The log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at Vilspa. It was constructed by using verified data from the IUE Final Archive Master Catalogue. The observations cover the whole life of the satellite, from March 1978 to September 1996.

- HaloSat targets to study the hot Galactic halo

- Description:
- HaloSat is a small satellite (CubeSat) designed to map soft X-ray oxygen line emission across the sky in order to constrain the mass and spatial distribution of hot gas in the Milky Way. The goal of HaloSat is to help determine if hot gas gravitationally bound to individual galaxies makes a significant contribution to the cosmological baryon budget. HaloSat was deployed from the International Space Station in 2018 July and began routine science operations in 2018 October. We describe the goals and design of the mission, the on-orbit performance of the science instrument, and initial observations.

- Description:
- The Herschel Space Observatory (Herschel) is an ESA (European Space Agency) project with instruments funded by ESA member states. It was operated from May 2009 till April 2013, offering unprecedent observational capabilities in the far-infrared and submillimetre spectral range (55-671 microns). Herschel carried a 3.5m diameter passively cooled Cassegrain telescope. The science payload comprised three instruments: two direct detection cameras/medium resolution spectrometers, PACS and SPIRE, and a very high-resolution heterodyne spectrometer, HIFI. Herschel successfully made over 37,000 scientific observations.

- Description:
- This catalogue is a copy of the Archived Exposures Catalog (AEC) compiled from the Hubble Space Telescope Data Archive database, with an indication about the existence of scientific images or spectra. It provides a summary of completed HST science observations. This catalogue contains also WFPC2 observations stacked into associations which usage is recommended for a large fraction of the WFPC2 images (see details in the "WFPC2 Associations" section below).

- Description:
- The Infrared Space Observatory (ISO) is an ESA (European Space Agency) project with instruments funded by ESA member states (especially the PI countries France, Germany, The Netherlands and the United Kingdom) and with participation of ISAS (Japan) and NASA (USA). It was operated from November 1995 till May 1998, almost a year longer than expected. As an unprecedented observatory for infrared astronomy, able to examine cool and hidden places in the Universe, ISO successfully made nearly 30,000 scientific observations. The ISO Data Archive is available at the ISO Data Centre at https://www.cosmos.esa.int/web/iso it includes about 150,000 observations, if account is taken of calibration and parallel or serendipity mode observations. The catalogue contains all observations performed in standard observing modes exempt from technical problems; special flags indicate calibration observations.

- Description:
- The JCMT Science Archive (JSA), a collaboration between the CADC and EOA, is the official distribution site for observational data obtained with the James Clerk Maxwell Telescope (JCMT) on Mauna Kea, Hawaii. The JSA search interface is provided by the CADC Search tool, which provides generic access to the complete set of telescopic data archived at the CADC. Help on the use of this tool is provided via tooltips. For additional information on instrument capabilities and data reduction, please consult the SCUBA-2 and ACSIS instrument pages provided on the JAC maintained JCMT pages. JCMT-specific help related to the use of the CADC AdvancedSearch tool is available from the JAC.

- K2/HARPS measurements for 8 stars

- Description:
- One of the best ways to improve our understanding of the stellar activity-induced signal in radial velocity (RV) measurements is through simultaneous high-precision photometric and RV observations. This is of prime importance to mitigate the RV signal induced by stellar activity and therefore unveil the presence of low-mass exoplanets. The K2 Campaign 7 and 8 fields of view were located in the southern hemisphere, and provided a unique opportunity to gather unprecedented simultaneous high-precision photometric observation with K2 and high-precision RV measurements with the HARPS spectrograph to study the relationship between photometric variability and RV jitter. We observed nine stars with different levels of activity, from quiet to very active. We first probed the presence of any meaningful relation between measured RV jitter and the simultaneous photometric variation, and also other activity indicators (such as BIS, FWHM, logR0'HK, and F8) by evaluating the strength and significance of the monotonic correlation between RVs and each indicator. We found that for the case of very active stars, strong and significant correlations exist between almost all the observables and measured RVs; however, when we move towards lower activity levels the correlations become random, and we could not reach any conclusion regarding the tendency of correlations depending on the stellar activity level. Except for the F8 whose strong correlation with RV jitter persists over a wide range of stellar activity level, and thus our result suggests that F8 might be a powerful proxy for activity-induced RV jitter over a wide range of stellar activity. Moreover, we examine the capability of two state-of-the-art modeling techniques, namely the FF' method and SOAP2.0, to accurately predict the RV jitter amplitude using the simultaneous photometric observation. We found that for the very active stars both techniques can predict the amplitude of the RV jitter reasonably well; however, at lower activity levels the FF' method underpredicts the RV jitter amplitude.
