Measuring second excited state |2> using "calibrations" not Open Pulse

Question

I am tying to measure the second excited state in a system that does not support Open Pulse. Instead I am using calibrations. The method detailed here does not work. I get the error "AttributeError: 'IBMQBackend' object has no attribute 'instruction_schedule_map'".

Using the method detailed here reproduces the same error "AttributeError: 'NoneType' object has no attribute 'instruction_schedule_map'".

Is there a different way to access the measurement calibrations in a system which does not support pulse?

I found the answer on my own. In case someone has a similar problem:

You can use the standard measure() function in the quantum circuit. When you assemble you can specify meas_level=1 which returns the raw measured data without running it through a classifier. Then you can build your own classifier.
