This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

4. Upper Limits for Sources not Detected
Next: Discussion Up: The Second EGRET Catalog Previous: First Catalog Sources . In the first EGRET catalog, upper limits were given for selected objects not detected during the Phase 1 all-sky survey. These upper limits are determined using the likelihood calculation and depend on the EGRET exposure to a given direction, the contribution of the diffuse gamma radiation, and the proximity and strength of detected sources. ...

... 2015 . ... Observations using the Arecibo S-band (2380 MHz, 12.6 cm) planetary radar system started in 1976 and its power and sensitivity were greatly improved with the telescope upgrade and Gregorian-dome installation in the mid-1990s. Below, we show the number of near-Earth asteroids attempted and detected since the radar program resumed in 1998. ... The number of NHATS objects detected with Arecibo similarly jumped in 2012, and 2015 was again a record year, where we detected 23 of these objects. ...
