Flat Spectrum Pulsar

From Scott Ransom: 

XTE J1810-197                                                                                    
Position is (J2000):  18:09:51.1,  -19:43:42.0  
Spectral index is probably around -0.5 (although it seems variable) and                                                 
the average flux density is a few tenths of a mJy.  Peak flux is 10-50                                                  
times higher, though, since the pulse profile is only 5-10% of the                                                      
pulse period (which is 5.5 sec).
