The single and double pattern fractions are highly sensitive to pile-up effects in bright sources and in case of deviations from the model curves (at energies of about double the peak energy) wrong spectral fit results are expected. ... epatplot can then be used to verify the event pattern fractions in the remaining area used for the spectrum. ...

Observations from the HERschel Inventory of the Agents of Galaxy Evolution (HERITAGE) have been used to identify dusty populations of sources in the Large and Small Magellanic Clouds (LMC and SMC). We conducted the study using the HERITAGE catalogs of point sources available from the Herschel Science Center from both the Photodetector Array Camera and Spectrometer (PACS; 100 and 160 ЮМm) and Spectral and Photometric Imaging Receiver (SPIRE; 250, 350, and 500 ЮМm) cameras. ...

Existing studies of the atomic hydrogen gas content in distant galaxies, through the absorption of the 21-cm line, often infer that the total column density is anti-correlated with the linear extent of the background radio source. We investigate this interpretation, by dissecting the various parameters from which the column density is derived, and find that the relationship is driven primarily by the observed optical depth, which, for a given absorber size, is anti-correlated with the linear size. ...
