This folder is foreseen as archive for lightcurves for solar radio spectrometers, e.g. Callisto.
The plan is to provide up to 5 lightcurves per day per instrument.
The main issue is to define a frequency channel which is clean from rfi.
I decided to search for Radio Astronomy frequencies in the FIT-files, according to the ITU list of RA frequencies
In case there is more than one channel in the Callisto range, then the channel is selected which
has lowest mean-value AND lowest standard deviation, assuming it contains lowest level of rfi.
As input for the decision about frequencies the first FIT-file found per day is used.
The y-axis, expressed as Y-factor in dB is a measure of the signal with respect
to the minimum of the light curve within this specific day.
Light curves are box-car filtered over 40 pixels, corresponding to 10 seconds integration time
It allows to find out whether the istrument:
- is working at all
- gives an impression about noise
- gives an impression about rfi (level and cadence)
