Description |
|---|
| EXPMAP |
The exposure map records the variation of the accumulated exposure time (in seconds) of 2D image mosaic and 3D IFU data cubes per pixel and per spaxel, respectively. It encodes the pattern of multiple offset exposures being combined into the final product while taking any possible masking of bad or invalid pixels into account. |
| GAINMAP |
The gain map (e-/ADU) specifies for each pixel the number of electrons that contributed to one ADU in that pixel of an image. |
| MASK |
The mask image describes the data quality of an image array by flagging bad pixels using integer numbers >0. |
| WEIGHTMAP |
Describes the pixel-to-pixel variation of the statistical significance of the image array in terms of a number that is proportional to the inverse variance of the background, i.e. not including the Poisson noise of sources. Also known as confidence map. |
| IMAGE.WHITELIGHT |
2D image obtained by averaging the data cube along the wavelength axis between WAVELMIN and WAVELMAX. Also known as broad-band image. |
2DSPECTRUM
|
2D array with one axis oriented along the dispersion direction (calibrated in wavelength), the other axis being the spatial dimension, normally oriented along the slit. Wavelength calibrated and distortion corrected 2D spectra can be submitted as associated files of the SCIENCE.SPECTRUM product |
| CCF |
2D array containing the cross correlation function of fibre A with a stellar template spectrum, computed per Echelle order. Each row represents one order, and the X direction is the sampling in velocity space. |
| CUBE.IFS.NO_TELLCORR |
A 3D data cube that contains the data calibrated but without the telluric correction. |
| CUBE.IFS.STD |
3D data cube of a standard star.
FITS data cube with the same dimension as the science data cube. |
| DRIFT |
2D array showing the drift in km/s as measured from the wavelength correction. It shows how much the wavelength reference system of one fibre moves with respect to the other. |
| FEROSTAR |
TAR file containing various r.FEROS* pipeline product files and an HTML summary page of the reduced products, including plots which may be useful for making a quick evaluation of the data quality. The TAR files contain several types of files, both FITS and non-FITS. |
| FILTERED |
Filtered image used to optimally extract compact sources. FITS image with the same geometry (NAXISi) and the same physical units (BUNIT) as the flux map. |
| FORS2TAR |
TAR file containing previews related to the individual exposure spectra that were combined: reduced 1d spectrum, 2d spectrum before and after sky correction. The extracted spectrum is highlighted. |
| HARPSTAR |
TAR file containing several types of files, both FITS and non-FITS.
|
