# 1. Increment loop counter and print message
# 2. request tonemap between PLD1 and PLD2; save in MAP
# 3. read OLD prescalars and write NEW prescalars based on MAP; only

# 5. plot prescalars from PIB discarding unwanted lines;

# 8. wait some time
# 9. load OLD prescalars into PIB
# 10. print a message
# 11. download and flash PIB to sample changes;
