Detailed_Input sc is the NAIF ID number for the spacecraft whose clock string is being converted. clkstr is a character string representing a spacecraft clock time, WITHOUT PARTITION NUMBER. ... scencd_c converts a clock string to the number of ticks it represents since the beginning of the mission, and so uses partition information. sctiks_c just converts to absolute ticks. ... The SCLK string includes a partition number. ...

Next: On-Line Catalog Information Up: The Second EGRET Catalog Previous: Discussion . ... The 91 sources with include the LMC, 40 sources identified with active galactic nuclei (AGN) with high confidence, 11 sources which may be AGN, and 39 unidentified sources. 31 sources reported in the first EGRET catalog do not appear in this catalog. 5 of these are sources which were identified with AGN; all 5 of these now have statistical significance just below the threshold for the present catalog. ...

The yellow arrow in the picture identifies the position of the black hole transient inside Centaurus A. The location of the object is coincident with gigantic dust lanes that obscure visible and X-ray light from large regions of Centaurus A. Other interesting X-ray features include the central active nucleus, a powerful jet, and a large lobe that covers most of the lower-right of the image. ...
