... flspec computes the spectrum of the background fluctuations in EPIC Imaging data. ... 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). ... Once created, positive and negative spectra are subtracted to obtain the 'fluctuations' spectrum in each annular region. ...

Next: The Echelle Relation Up: Wavelength Calibration Previous: Wavelength Calibration . A preliminary step to the wavelength calibration consists of extracting the orders of the WLC image which can then be used to determine the dispersion relation in two steps: . ... Both methods are based on the echelle relation and therefore are not applicable if the disperser is not an echelle grating, as it is the case for EFOSC which involves a grism disperser. ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...

... Description . ... The SCORPIO-2 project: . ... The multi-mode spectrograph SCORPIO-2 was developed using the experience of observations at the 6-m telescope BTA with the SCORPIO focal reducer . ... The focal reducer consists of several units ('floors') mounted in the common case in the following order (from the telescope focal plane): . ... The focal reducer is connected with the platform-adapter which used for guiding by offset stars and for illumination the spectrograph by calibration lamps. ...

... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...
