| + | First try of scheduling and performing observations from Hobart26 as one-station experiment: (by David Schunck) | ||
| + | |||
| + | * I rebuild a VEX file based on the observations from 2016 ([[wg7:gnss_vlbi:2016:g336:g336|g336]]) | ||
| + | * VieVS is only using the function "degree2dms" from the Mapping Toolbox to reform //declination// angles for the VEX file. This function was reimplemented as the toolbox was not available. Also, "degree2hms" was implemented for the //right ascension// angle. | ||
| + | * The VEX file needed to be adjusted significantely in order to run it. Guifre was a big help and Jamie, after some fiddeling around, was finally able to run it. | ||
| + | * The first observation was scheduled on 23/04/2021. Unfortunately, I made a mistake when using the results of my reimplemented matlab function to write it in the VEX file. A "-" was missing for the negative declination angles which ran the telescope into its limits. | ||
