Description
|
dataType
|
DataSourceDataType
|
1..1
|
FID, part-processed, processed, other,or whatever.
|
details
|
String
|
0..1
|
Free text, for notes, explanatory comments, etc.
|
isNormalStorage
|
Boolean
|
1..1
|
Can this file be read using the normal storage algorithms. Default true. E.g. Kay type P+/-N storage has False for this parameter
|
isSimulated
|
Boolean
|
1..1
|
Is the DataSource simulated rather than measured?
|
name
|
Line
|
1..1
|
name of DataSource
|
noiseLevel
|
NonNegativeFloat
|
0..1
|
Estimated noise level for a spectrum, defined as the estimated standard deviation of the points from the baseplane/line.
|
numDim
|
Int
|
1..1
|
Number of dimensions - may be different from the numDim of the Experiment to which the DataSource belongs (e.g. projections).
|
numShapes
|
NonNegativeInt
|
1..1
|
Number of shapes in each matrix decomposition component. If set to zero the data are not decomposed by shape - which is the normal case.
|
numSparsePoints
|
NonNegativeInt
|
1..1
|
Number of time increments acquired. If nonzero, this signifies that the original data are sparsely sampled - otherwise it can be derived from the size of the grid. Note that this counts the number of time steps, a hypercomplex point counts as one point even if it requires eight real numbers to describe it.
|
recordNumber
|
Int
|
1..1
|
Number of record (starting at zero) of data record in dataStore. May or may not be relevant, depending on the type of dataStore
|
scale
|
Float
|
1..1
|
Scaling factor for intensities and volumes in a given datasource, for use when comparing intensities etc. between spectra. Intensities and volumes should be *multiplied* by scale before comparison, so that a scale of e.g. 10.0 means that the intensities are ten times larger than reflected by the numbers stored in the file.
|
serial
|
Int
|
1..1
|
Serial number of object. Serves as object main key. Serial numbers of deleted objects are not re-used. Serial numbers can only be set by the implementation. Values are in practice always positive, since negative values are interpreted as a signal to set the next free serial
|
signalLevel
|
NonNegativeFloat
|
0..1
|
'Standard' signal level, estimated according to signalLevelMethod. the snRatio is defined as signalLevel/noiseLevel.
|
snRatio
|
NonNegativeFloat
|
0..1
|
Derived. S/N ratio, calculated as signalLevel/noiseLevel.
|
storageDetails
|
String
|
0..1
|
Text description of storage for cases not covered by standard algorithms (isNormalStorage false).
