Field Documentation

bad

int** image::bad

The bad pixel mask, by panel

bw

double image::bw

Full-width half-maximum bandwidth as a fraction, applied to wavelength

crystals

struct crystal_refls* image::crystals

Array of crystals (with reflection lists) in the image

data_block

void* image::data_block

The data block, e.g. received over ZMQ, for the image. filenename/ev OR this should be filled in, but not both

detgeom

struct detgeom* image::detgeom

The detector structure

div

double image::div

Convergence angle of the incident ration, in radians (full angle)

dp

float** image::dp

The image data, by panel

features

ImageFeatureList* image::features

List of peaks found in the image

header_cache

struct header_cache_entry* image::header_cache[HEADER_CACHE_SIZE]

A list of metadata read from the stream

hit

int image::hit

Non-zero if the frame was determined to be a "hit"

id

int image::id

ID number of the worker processing handling this image

ida

ImageDataArrays* image::ida

Re-usable data array structure, or NULL if not used

indexed_by

IndexingMethod image::indexed_by

Indexing method which indexed this pattern

lambda

double image::lambda

Wavelength of the incident radiation, in metres

n_crystals

int image::n_crystals

The number of crystals in the image (size of crystals)

n_indexing_tries

int image::n_indexing_tries

Number of times the indexer was tried before succeeding

owns_peaklist

int image::owns_peaklist

If set, then 'features' should be freed with the image. Otherwise, it is managed externally (e.g. by Julia)

peak_resolution

double image::peak_resolution

Resolution estimate based on peaks

sat

float** image::sat

The per-pixel saturation values, by panel

serial

int image::serial

Monotonically increasing serial number for this image

spectrum

Spectrum* image::spectrum

Spectrum information
