21.1 The raster maps using a standard CIA procedure (see text for details). Left panel
shows the LW3 data, while the right panel shows the LW2 data. Both data sets
are affected by periodic patterns due to bad flat-field determination, as well as
long term transients. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 278
21.2 The resulting maps for the Perturbed Single Flat-Field determination. Note
that the map orientation has changed as SLICE always produces maps with
North up and East left. Imprints of the individual raster pointings are still visible.282
21.3 The resulting maps for the first flat-field determination with the DivSky. Note
that the “emission gradient”, produced by the long-term transient is much smoother
now, and pointing imprints are mostly gone. . . . . . . . . . . . . . . . . . . . . . 284
21.4 An example of artifacts obtained with a incorrect long-term transient determination:
the signal oscillates and the number of complete oscillations is roughly
equal to half the number of raster legs. The dashed line represent the fitted correction
(see text for details). In fact, these artifacts were generated while using
the DivSky flat-field method in the long-term transient determination for the
LW3 image. The LW2 image shows similar problems. . . . . . . . . . . . . . . . . 285
21.5 The long-term transient corrections derived by SLICE. The continuous curves
are the exact corrections and the dashed ones the fitted corrections, assuming the
long-term transient effect is a combination of two exponentials. On the left, the
LW3 case, and on the right, the LW2 case. Some oscillation appear on the LW2
exact curve, but these are not obviously related to the raster scan period. . . . . 286
