Next: Data reduction Up: Spectral observations and data Previous: Observations with the KPNO . Follow-up spectroscopy with this telescope was conducted as a back-up for a main program which needed photometric conditions. So, the observations presented here were obtained in non-photometric conditions and the absolute flux calibration of the data is unreliable. The Cassegrain focal reducer CAFOS of the 2.2m telescope was used with a long slit of 300 3 and a grism of 187 ? ...

... Detailed comparisons with ALMA observations (left) with numerical models (right) enable us to develop observing strategies for ALMA, to plan, optimize, and interpret observations, and to demonstrate that potentially important scientific results can be expected from solar ALMA observations. ... The Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) was initiated in 2014 in connection with two ALMA development studies. ...

... Within SAS, a tool is available to check the pile-up fraction in the pn data: epatplot . This tool compares the observed pattern distributions (derived from a pn calibrated and concatenated even list) with the calibrated models. ... The lower panel is the key element for the evaluation of the pile-up fraction: it shows the observed distribution of pattern as a function of energy (PI channel in Analog-Digital Units ), using the same color code. ...

... Our scientific interest is an accuracy of asteroid CCD observations obtained by amateurs and professional astronomers all over in the World. ... These data help us to analyse an accuracy of real CCD positions in the MPC Database. ... Do you test your observations of the small Solar System bodies permanently before sending them to the International Minor Planets' Center? ... Do you know a real accuracy of your positional CCD-observations in comparison with the other observatories' one ? ...

... As modern observatories evolve to production units delivering data products and calibrated scientific data to the end users, new challenges arise in assessing the quality of data products. ... Taking the analogy of speed control on a motorway we can describe the system as a device (radar) collecting measurements of the system performance (passing cars). ... One of the direct applications of quality control is the verification of instrument performance based on the analysis of calibration exposures. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
