+ | It takes the raw VLBI data, reads any desired channel and performes a high-resolution integrated-time FFT of the entrie scan. It uses an initial settings file (inifile.ini). I usually store the inifile.ini in the same folder with the results. There are several settings that can be modified. However, the main ones are: | ||
