Be an INTEGRAL astronomer: Task 3
 |
By examining the data for these objects from 2005 to 2009 what can you say about how they vary? (Hint: Do they vary in a regular way? Is there a pattern?)
Indicate how the X-ray emission of these sources compares to that from the Crab. (Hint: compare the average count rates for the sources and when the source is at its brightest how does it compare to the Crab?.)
| Source name | Source type | Data |
| GX 5-1 | X-ray binary | |
| GX 354-0 | X-ray binary | |
| GX 1+4 | X-ray binary pulsar |
