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. ...

... This thread contains a step-by-step recipe to extract MOS spectra of a point-like source observed in Imaging mode and to create associated response matrices, starting from a calibrated, concatenated event list (either produced with emproc or available as PPS product; here it has the assumed file name MOS.fits ). ... The users should note that the SAS metatask xmmselect allows them to interactively define source and background regions (via ds9) and to run backscale on the fly. ...

... Light sources: POV-Ray works with point sources of light. ... A real star consists of a spherical light source (the photosphere where the continuum is formed) superimposed by a scattering layer (an atmosphere) responsible for phenomena such as limb darkening and absorption lines. ... For example, in order for the central light source to illuminate the surface, the star must be transparent. ... The POVRay source for creating the white dwarf binary merger movie is given for demonstration purposes. ...

... The generation of simulated sources whose physical properties are well understood is useful in assessing the functionality of point source analysis software. Qpsim is an IRAF/PROS task which will generate events from sources of given intensity, shape, and position and either overlay them on a flat background in a new QPOE file or inject them into an existing QPOE file. ... The simulated data can be a useful tool in calibrating point source analysis software. ...
