DRS4TimelapseFitter

class lstcam_calib.tools.create_drs4_timelapse_file.DRS4TimelapseFitter(**kwargs: Any)

Bases: Tool

Tool to fit the dt curve coefficients.

This tool is the third and final tool used to perform dt curve fitting. It runs on the output of lstcam_calib_create_drs4_dt_file from which it computes the dt curve fit parameters, either for each individual pixel or per batch (old or new) of drs4 chips.

Attributes Summary

aliases
flags
group_by	This options determines how the fits are performed.
input_path	A path Trait for input/output files.
mean_threshold_old	DRS4 chips with a higher mean value than this at dt=10ms are classified as 'old' chips
name
output_path	Output file of drs4 time lapse correction (fits or hdf5 automatically selected dipending on suffix)
plot_output_path	PDF file with plots of baseline vs dt and fit results
progress	A boolean (True, False) trait.
t0_fixed	Whether to hold the t0 parameter fixed in the fit.
t0_new	Fixed t0 value for new batch DRS4 chips.
t0_old	Fixed t0 value for old batch DRS4 chips.

Methods Summary

finish()	Store output.
setup()	Set up the tool.
start()	Fit data of each pixel.

flags: StrDict = {'no-progress': ({'DRS4TimelapseFitter': {'progress': False}}, "don't show a progress bar during event processing"), 'no-t0-fixed': ({'DRS4TimelapseFitter': {'t0_fixed': False}}, 'Have t0 as free parameter in the timelapse fit'), 'progress': ({'DRS4TimelapseFitter': {'progress': True}}, 'show a progress bar during event processing'), 't0-fixed': ({'DRS4TimelapseFitter': {'t0_fixed': True}}, 'Keep t0 fixed for the timelapse fit')}

group_by

This options determines how the fits are performed. If ‘pixel’, one fit is performed per pixel/channel combination. (1855 * 2). If ‘batch’, one fit is performed per batch of drs4 chips (1 or 2). This also influences the output data format.

input_path

A path Trait for input/output files.

Attributes:

exists: boolean or None

If True, path must exist, if False path must not exist

directory_ok: boolean

If False, path must not be a directory

file_ok: boolean

If False, path must not be a file

mean_threshold_old

DRS4 chips with a higher mean value than this at dt=10ms are classified as ‘old’ chips

name: str | Unicode[str, str | bytes] = 'lstcam_calib_create_drs4_dt_file'

output_path

Output file of drs4 time lapse correction (fits or hdf5 automatically selected dipending on suffix)

plot_output_path

PDF file with plots of baseline vs dt and fit results

progress

A boolean (True, False) trait.

t0_fixed

Whether to hold the t0 parameter fixed in the fit.

t0_new

Fixed t0 value for new batch DRS4 chips.

t0_old

Fixed t0 value for old batch DRS4 chips.

Methods Documentation

finish()

Store output.

setup()

Set up the tool.

This method runs after the configuration and command line options have been parsed.

Here the tool should construct all Components, open files, etc.

start()

Fit data of each pixel.
