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.

Current measurements of the positron cosmic rays exhibit a bump around 10 GeV which is still hardly explained by standard secondary astrophysical processes, i.e. spallation of cosmic rays off the interstellar gas. Many scenarios have been invoked as potential solutions to this excess, among them being some additional primary positrons originating from dark matter annihilation in the Galaxy.
While the PAMELA satellite is about to yield much more precise data, it is of paramount importance to theoretically constrain the expected secondary positron flux before any putative interpretation of the observations. Moskalenko and Strong (1998) provided a precise estimate some years ago, but using rather old parameterizations for the nuclear cross sections, and without giving the theoretical uncertainties affecting their predictions.
We reestimate the secondary positron flux by using and comparing different up-to-date nuclear cross sections and, and by considering an independent model of cosmic ray propagation. We also carefully study the origins of the theoretical uncertainties.
