i4ds / ecallisto_ng Goto Github PK

If I import the package and want to run the example, I need to replace ecallisto_ng by src.ecallisto_ng

I had to install pandas separately

For 90% of instruments and measurements, the current database schema works fine. However, for the remaining 10%, the number of frequencies are changed too often and thus too many columns are being created.

Another method would be to:

• Change all the column names to freq_1, freq_2, .., freq_n
• Add another column called frequencies, which contains an int
• Create another table, containing an array with the frequencies and the int, corresponding to a measurement and it's frequencies
• Each time a new measurement is added, we check if this range of frequencies exists. If not, increment the int by one and add it as an array.

Example:
|frequencies|freq_id|
|[1,2,3,4,5]|1|

Main table:
|freq_1|freq_2|..|freq_192|freq_id|
1|7|..|3|1
