Dear friends,
Please find enclosed the list of found sources by Midisky for JEM-X1
during the recent GCDE observation of revolution 240. There are 8 known
sources, the last one "4U 1722-30" is not found by OSA 4.1. I think the
five unknown sources are all spurious: Nb 8 ("UIGR_27035-2512") is inside
the large spot made by GX5-1 on the images; the strong N:9 ("UIGR_27223-2604")
is just a misplaced identification of GX5-1 (exactly 2 deg. away) due to
wrong attitude info for the pointing 67.
Kind regards,
Jérôme

Hi Jerome,
Addendum: In orbit 240, pid 112 I see a burst of ~30 sec from a source (ra
266.87,dec -30.05) which is very close to SLX 1744-300 (ISDC catalog). The peak
intensity is 0.5 Crab (3-15 keV).
Best regards
Carl
Hej carl,
Yes, I might have been too hungry and looked too quickly at my mosaic
images... :-)
So, I can add at least four other known sources not listed in the previoulsy
email (that is, not automatically detected) but visible on the mosaic images:
GRS 1758-258 (only in the two highest energy band)
SLX 1744-300
SLX 1735-269
1E 1743.1-2843 (but it seems to be ~1.5' away from its catalog position)
Cheers,
Jérôme
