We compare X-ray fluxes measured within the first all-sky survey conducted by the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) instrument on board the Spectrum-Roentgen-Gamma (SRG) observatory to CaII H &amp; K excess flux measurements, using observations made with the robotic TIGRE telescope.</description><source format="bibcode">2022A&amp;A...661A..24F</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/661/A24</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A1">J/A+A/661/A1 : The eFEDS X-ray catalogs (V7.4) (Brunner+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A2">J/A+A/661/A2 : Galaxy clusters and groups in eFEDS (Liu+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A3">J/A+A/661/A3 : eFEDS counterparts to point-like sources (Salvato+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A4">J/A+A/661/A4 : eFEDS optical cluster and group catalog (Klein+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A5">J/A+A/661/A5 : The eFEDS AGN catalog (Liu+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A7">J/A+A/661/A7 : X-ray properties of eFEDS clusters and groups (Bahar+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A8">J/A+A/661/A8 : eFEDS catalogue of variable X-ray sources (Boller+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A10">J/A+A/661/A10 : eFEDS galaxy clusters and groups in disguise (Bulbul+, 2022)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/661/A23">J/A+A/661/A23 : Exoplanet X-ray irradiation &amp;
