Specific heat data in GaAs/AlGaAs at 5/2 filling fraction: 20201121 data set

Each data set name incorporates the date in which the data was acquired. There are a total of 6 data sets as shown in the table below (the current one, 20201121, is part of it). In each data set there is a series of txt files (current one has 30) that contain relevant information about the dataset such as the magnetic field (both relative B* and absolute values), the FQH state as well as a table with the raw data file names and the corresponding quantities of interest (input square wave DC offset + amplitude in Volts, set temperature in Kelvin, mean/uncertainty of/in temperature in Kelvin, signal samples - averaging, resistor values in Ohms, gain, frequency in Hertz, time stamp and time difference between each acquisition in seconds). The name of these information files is composed of the date in which the data set was acquired, the cooldown number, the sample name/number and the conductance (G) followed by the file number (increment of 1). Furthermore, each data set contains all the raw data save in txt files (current one has 570). The name of each file begins with Zurich (ZH) is followed be the cooldown number, the date in which the dataset was acquired, the row number of the data matrix (for each new thermal bath - dilution refrigerator temperature) and the column number of the data matrix (for each different input voltage - i.e. square wave DC offset + amplitude at the same thermal bath - dilution refrigerator temperature). Each raw data file contains 2 columns. The first column is the time in seconds. The second column is the voltage drop across the sensing 1 kilo Ohm resistor in Volts (which translates to current across the Corbino device). This is the raw response (to the bipolar square wave input) of the 2D electron gas (2DEG) measured by the Zurich digitizer.
