In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Sub-milliarcsecond resolution measurements of stars with Cherenkov telescopes
Imaging Atmospheric Cherenkov Telescopes (IACTs) currently represent the most sensitive instruments to study the very-high-energy gamma-ray sky (from 50 GeV to ~ 10 TeV). Over the last few decades, the current generation of IACTs (MAGIC, HESS and VERITAS) have consolidated their relevance within the astroparticle physics field on topics such as fundamental physics, Dark Matter searches and high-energy astronomy. In order to detect the Cherenkov flashes of blue light produced within extended air showers, these telescopes need very large mirror surfaces and cameras operating at nanosecond timescales. Interestingly, these technical capabilities serendipitously make them suitable Stellar Intensity Interferometers (SII), allowing them to perform high-angular-resolution observations. CIEMAT has been deeply involved in the validation of this technique, and has just completed an upgrade of the MAGIC telescopes allowing them to routinely perform SII measurements. The state of the art of high-resolution optical astronomy will be presented, together with the firstobservations taken with the new MAGIC-SII setup.
