full_statistics

If True, write spike{1,2,3} mean, count, std for each capacitor. Otherwise, only mean spike height for each gain, pixel is written

output_file

Output file of pedestal baseline and spike heights (fits or hdf5 automatically selected depending on suffix)

overwrite

If true, overwrite output without asking, else fail if output file already exists

skip_samples_front

Do not include first N samples in pedestal calculation

Methods Documentation

check_baseline_values(baseline_mean)

Check the values of the drs4 baseline for issues.

In case of no EVBv5 data or no pre-calibration by EVBv6, we expect no negative and no small values.

In case of EVBv6 applied baseline corrections, values should be close to 0, but negative values are ok.

finish()

Compute and write-out calibration coefficients.

mean_spike_height()

Calculate mean spike height for each gain, pixel.

setup()

Perform initial setup.

start()

Run main event loop.
