Pointing Errors Module

X direction). The standard deviation for the absolute pointing error, as well as the percentage for the relative pointing error, are user defined parameters and can be modified.

The thermal system includes the Warm Optics Module and the Cold Optics Module, which given the optical set-up and the optical parameters of the different optical elements calculates the transmission of the sky map through the instmment. At this point the physical properties of the instrument are defined and the Double Fourier Modulation can be performed at the Double Fourier Module. Here is where the interferograms are computed analytically for different baseline positions. If pointing errors are selected, the Pointing Errors Module generates them and they are fed to the Double Fourier Moduie. 

PointingErrors allows pointing errors to be included in the Double Fourier Modulation. 

In the MV-map generator module, accounting for the slewing time of the telescopes will be interesting in order to compute the total observation time, as well as fuel calculations. Related to this, the pointing errors of the telescope need to be simulated not only for the different telescope positions, but also the pointing errors during an FTS scan will need to be modelled. To model these some software optimisation is required because this process is computationally heavy. 

It is possible to identify particular spectral features in the modulated reflectivity spectra to band structure features. For example, in a direct band gap the joint density of states must resemble that of critical point. One of the first applications of the empirical pseudopotential method was to calculate reflectivity spectra for a given energy band. Differences between the calculated and measured reflectivity spectra could be assigned to errors in the energy band... 

Microwave switches are beam-breaker-type point sensors with an accuracy of 13 mm (0.5 in.) and with pressure and temperature ratings up to 28 bar (400 psig) and 300°C (600°F). Pulse-type radar gauges have ranges up to 200 m (650 ft) and are accurate to 0.5% FS, whereas frequency-modulated carrier wave (FMCW) units have errors from 1 to 3 mm (0.04-0.125 in.). Their pressure and temperature ratings are up to 80 bar (1,200 psig) and up to 400°C (750°F). 

Prescriber Order Entry Module (POEM ) provides a database of the most common medication orders. These orders are specific to drug, route of administration, formulation, age, indication/use, and weight or body surface area, if applicable. This enables more accurate and efficient point-of-care computerized order entry applications to prevent errors at the prescribing stage of drug delivery. 

More than one ground generates noise and signal transmission errors. To reduce this possibility, isolation modules can be used to physically detach the DC common return between the two ground points as shown in Figure 10-12. 

RF piekup from the exeitation source or crosstalk between the deteetor and the referenee lines eauses systematie timing errors. The result is a modulation of the effeetive CFD threshold and the effective CFD zero cross point. Modulation of the threshold modulates the deteetion efficiency. Modulation of the zero cross point warps the time axis. In either ease the result is a ripple in the recorded curves. 

If the required phase correction is not an integer, two options are possible (1) round the phase correction to the nearest integer pixel index and accept a timing error of not more than one-half of the sample interval or (2) resample the data so that the resample point is precisely at the start of the modulation cycle. The first option typically is preferred because it maintains the original data, without introducing resampling errors, and is computationally simpler.
