Commentary

Frank Marshall writes:

This reports the results of my "blink test" on the E-W scans
of the bulge on March 22nd.

* XTE J1819-254 remains bright with a peak obs. counting rate of about 154 cps.
* XTE J1710-281, the new eclipser, is about 20 cps.
* XTE J1723-376 remains bright at about 450 cps (4 PCUs)
*     J1742-363 is seen at about 17 cps (4 PCUs)
* The weak source near (265.8, -23.71) is still there.
* No bright new sources.

These scans were done at the new, reduced high-voltage settings for all
the PCUs. This should have a small effect on the counting rates.

A few additional items:

  * Either the Rapid Burster or 4U 1728-34 appears to have had a burst
    during the scan over it (near MET 164757220 = MJD 51259.9123).
    Unfortunately, the sources are so close together that their point
    spread functions overlap significantly, and it is not possible to
    definitively establish which source emitted the burst.

    The maximum count rate was about 7000 ct/s, and the episode lasted
    for about 6 seconds.  Quiescent emission is present after the
    burst, suggesting we actually saw the beginning and end of the
    burst.

    I have performed FFTs of the burst.  There are no significant
    oscillations at either 306 or 364 Hz, the expected frequencies for
    the Rapid Burster and 4U 1728-34, respectively.  The study of the
    energy spectrum is still an open question.  This may be hampered
    by the very recent gain change.

  * In any case, the Rapid Burster continues to decline.  I may have
    said "3 Crabs" last time.  I meant to say 300 mCrab.  Now it is
    down to about 30 mCrab.

Jean (in't Zand), I have limited access of the page to collaborators,
namely Goddard and purple.sron.nl.  Let me know if you need any other
hosts enabled.
