... sin f = y / r . cos f = x / r . ... They are now viewed as new definitions of the sine and cosine, for the polar angle f given by x and y ( a slightly different way of formulating this definition is described further below ). ... sin 2 f + cos 2 f = 1 . ... Angle . ... Many trigonometry texts define the sine and cosine slightly differently, using the so-called unit circle . ... Then the distance AB ("the sine line") equals sin a , and the distance OA ("the cosine line") equals cos a . ...

Both gripes from users and continued spectrum monitoring initiate in-house and off-site searches for the source of Radio Frequency Interference. The digital equipment used in various backends, frequency synthesizers at different mixing stages of the IF/LO, electric motors, video cameras used for safety-status monitoring, on-site vehicles, displays at the Visitor Center could in principle cause internally generated RFI. ...

DIGITAL WDC EXCHANGE FORMAT . FOR OBSERVATORY 1.0 MINUTE VALUES 1. ... DATA-1 .. DATA-60 are 1-minute values of the given element for that hour. ... Typically, digital 1-minute values received by WDCs from organizations operating automatic magnetic observatory instruments are averages of more frequendy sampled values, e.g. 10-second point samples. ... If the method used to obtain 1-minute average values is important to a user, the WDC will assist in determining the exact procedure applied. ...

... flspec computes the spectrum of the background fluctuations in EPIC Imaging data in different offaxis annular regions. ... Once the 'flatfielded' image is free from detected sources, its pixels are binned according to the input parameter binsize and classified as 'positive' (if they have more counts than the median in the image) and 'negative' pixels (less counts than the median). ... The positive and negative spectra are extracted with an spectral binning of 15 eV (MOS) and 5 eV (PN). ...

Next: Fitting of data Up: Extraction of Information Previous: Extraction of Information . For projects which perform statistical analysis on groups of objects, it is important to rely on an objective search method to extract them from the data frames. ... The simplest and fastest method is using a given level over a previously determined background value as the criterion to identify possible sources. ...

... We present the first results of a system for automatic analysis of astronomical images from digitized plates. This system will automaticallyidentifyspectral lines in low resolution spectra employing image processing and analysis. ... Our ob jective is to develop an algorithm of optimal and robust segmentation of stellar spectra on spectral plate images with the purpose of identifying its spectral lines in an automatic form. ... Processes for the automatic identification of spectral lines. ...

... 2 Small internal circular menisci (capillaries) Analysis of the profile curves of the small internal circular menisci in dependence on the various crystal radii was made for the external pressure Hd = -4 (in capillary constants). ... The dependences of the angle d on the external pressure and meniscus height on this angle for the small external menisci (fibers) are similar to the corresponding dependences for the case of small internal menisci (capillaries) (Fig. 2 c,d). ...

TUI supports the following offsets: . Object Arc offset by a given amount on the sky (i.e. along the arc of a great circle). ... Arc offsets are useful for moving a different portion of your object or a different nearby object onto the boresight . ... Object Arc XY this is identical to an Object offset except that it has been rotated to align along the instrument x-y axes. ... This is just like the Calibration XY offset, except that it is typically cleared when you slew to a new object. ...
