Associate a Shock at Earth with Flare and ... (2)

• Download

Using start date and end date all shock events at Earth are backpropagated to the Sun. Arround the time all flares (above certain levels) and cmes are assoicated. The possition of the flare and speed of the CME are used to forward propagate the event to Mars.

Connect flare events with proton events on... (4)

• Download

This workflow uses flares listed in the goes_sxf_flare list, checks wether this flare is connected to Earth via the Parker spiral, and looks for proton events at earth listed in the goes_proton_event list. The flare listing and the proton listing is combinded into a VOTable output.

Example of explicit looping (1)

• Download

This workflow demonstrates how a nested workflow can be called an explicit number of times. Note that the loop iterator does not need to be used in the logic of the loop contents. It can be used as a sentinel (see the conditional workflow)

• Download

Calculation of distances, corrected apparent B magnitude mB-corr and luminosities with values gathered from the HyperLEDA database. This workflow receives a list of galaxy names (hyperLEDA names. ie: KIG0001) and a file with the morphological types of those galaxies Using the name of a galaxy, the workflow querys Hyperleda to extract some properties of this galaxy (J2000 Coordinates, velocity, galactic extinction,log of axis ratio, and the Total B-magnitude ). With this properties it calcula...
