Notes on the "JEMX Analysis Users Manual" Issue 4.0, 19 July 2004,

Page 5: JEM-X 1 is currently dormant -> JEM-X 2

The JEM-X "2" unit is currently dormant. Due to the erosion of the microstrip
anodes inside the detectors only one JEM-X unit is in operation at a time.
Both units were switched on until December 29, 2002 when JEM-X2 became the only
one in operation until March 5, 2003, where JEM-X1 took over, because it has less
damages.

Page 47:  8.6 j_image_bin, First paragraph OK

The shadowgrams are made in a normal coordinate system when the hidden
parameter BIN_I_shdType = 3 (default value) as of OSA 4.2.

[Tabel 15 is not about parameters for j_ima_shadowgram but for j_image_bin; the
caption is a bit ambiguous]

Page 49: Figure 20 should be replaced with new shadowgram type.

8.7.1 j_ima_basic_recon

[After the first phrase the remarks on hexagonal coordinate system can be given, here
is a suggestion for a replacement of the second phrase:]

Due to the hexagonal pattern of cells on the mask the image reconstruction is done
in a skew coordinate system, see Fig. 19. An intermediate image is produced (JMXi-RSTI-IMA)
with an oval shape and from that a skyimage (JMXi-SKY.-IMA) is made by pixel remapping.

Table 17: [I think that ignoreAnode could be left out or marked as 'currently not used'.
           The upper limit for numPixelSubDiv is 30, not 500]

Page 69: [Figure 24 is obsolete - I'm embarrassed that it has survived so long. Shadowgram
          pixels are 1.00 mm and not 7.05mm/7. Please take it out as well as the reference
          to it.]

Table 45: [Values have changed. Please get new values from Carol Anne]



That's it - for the time being.
