Sentence examples for define a source from inspiring English sources

Normally i.e., when set_source is used to define a source model expression the model to be used as the PSF convolution model must be defined as such with the set_psf command; however, it is not necessary in this case since we are manually defining the full source model expression using the set_full_model functionality, as shown in the next section of this thread.

To describe the source contributions to the total emission in the spectrum, we define a source model consisting of an absorbed power-law multiplied by an absorbed thermal plasma model, to describe the bright central point source and the surrounding diffuse thermal gas, respectively.

Ideally, a case-control study should initially define a source population precisely, from which cases and controls are then randomly sampled.

To learn how to fully establish a PSF model when defining a source model with set_source, see the Sherpa thread Accounting for PSF Effects in 2D Image Fitting.

These variables will be used to assign the instrument response to the faked data set we will create in the next section, "Defining a Source Model Expression".

We have defined a source model expression for this simulation using an absorbed 1-D power-law model with a Galactic neutral hydrogen column density of 2×1021 cm-2 and a power-law photon index of 2. Simulating the Chandra spectrum means taking the defined model expression, folding it through the Chandra ACIS-S response, and applying Poisson noise to the counts predicted by the model.

A developer defines a source query in an external system, adds one or more transformations that manipulate data from a source query, and writes the results of the transformations to tables within the Medical Enterprise Data Warehouse.

The intensity integrated over a closed surface defining a source-free space compared to the sound pressure integrated over the same surface gives a measure of the capability of a specific intensity measuring system to suppress external noise.

The save_model function saves the 1D or 2D data arrays which define a convolved source model to a FITS table or ASCII file; the arrays are written as columns XLO, XHI, and MODEL.

Copying data led to heartache as companies try to define a data source of truth.

Müller (2001) proposed to define a spherical source in terms of the outward crack wall motion of a spherical crack.
