MythenDetectorSpecifications¶

MythenDetectorSpecifications contains all detector specific parameters, such as the number of modules, internal detector parameters like the strip width.

Note

The method read_bad_channels_from_file expects a text file using the format below. Each line denotes the index of a bad channel. Consecutive bad channels can be stored on one line e.g. channels with 20-42 are bad channels.

If youre file format deviates from the above format read youre file into a boolean aare::NDArray and pass to set_bad_channels directly. Alternatively implement your custom Filereader inheriting from SimpleFileInterface (SimpleFileInterface) and pass it to the constructor.

class MythenDetectorSpecifications¶

Public Functions

inline MythenDetectorSpecifications(std::optional<std::shared_ptr<SimpleFileInterface>> custom_file_ptr = std::nullopt)¶

constructor for MythenDetectorSpecifications

Parameters:: custom_file_ptr – (optional) pass Filereader to read bad channels file default If none is provided bad channel file is expected to be a text file where each line stores the channel index of a bad channel. Consecutive bad channels can be stored in one line by seperating the first and last channel index of the bad channel block e.g. bad_channel_index0-bad_channel_index1.)

inline MythenDetectorSpecifications(const size_t max_modules, const double exposure_time, const double num_counters = 1, double bloffset = 1.532, std::optional<std::shared_ptr<SimpleFileInterface>> custom_file_ptr = std::nullopt)¶

constructor for MythenDetectorSpecifications

Parameters:

max_modules – Number of modules in detector (default 48).
exposure_time – Exposure time [s].
num_counters – Number of counters active.
bloffset –
custom_file_ptr – (optional) pass Filereader to read bad channels file default If none is provided bad channel file is expected to be a text file where each line stores the channel index of a bad channel. Consecutive bad channels can be stored in one line by seperating the first and last channel index of the bad channel block e.g. bad_channel_index0-bad_channel_index1.)

inline void read_bad_channels_from_file(const std::string &filename)¶: read bad channels from file

Warning

only works if member custom_file_ptr supports reading the format

inline void set_unconnected_modules(const std::vector<ssize_t> &unconnected_modules)¶

inline NDView<bool, 1> get_bad_channels() const¶

inline void set_bad_channels(const NDArray<bool, 1> &bad_channels_)¶

set bad channels

Parameters:: bad_channels_ – boolean NDArray of size of total number of strips/channels in detector, stores ‘TRUE’ if strip is a bad channel otherwise ‘FALSE’

inline NDArray<ssize_t, 1> get_unconnected_modules() const¶

inline size_t max_modules() const¶: number of modules in detector (default ‘48’)

inline size_t num_counters() const¶

inline double exposure_time() const¶

inline double bloffset() const¶

inline double dtt0() const¶

inline ssize_t num_strips() const¶: total number of strips/channels in detector
