4. Overview of dark signal processing per product

The Dark Charge (DC) is a temperature-dependant signal added to the useful measurements and it is therefore substracted
from them during the processing. There are two phenomena that produce a continuous increase of the DC: the "hot pixels"
(a pixel is "hot" when its DC exceeds by a significant amount its value measured on ground at the same temperature) and
the "Random Telegraphic Signal" (abrupt change positive or negative of the CCD pixel signal, random in time, affecting
only the DC part of the signal and not the photon generated signal).
In this section a list of products that did not use the Dark Sky Area (DSA) observation for the DC computation is given.
It is also provided the mean DC plot per product for dark limb products with no error flag set.

4.1 These products did not use the DSA observation for DC computation:

4.2 Plot of mean dark charges per product: only products in DARK limb conditions without errors are used

5. Demodulation flag and quality information monitoring

In this section it is presented the modulation information extracted from the pcd (product confidence data)
at measurement level and information extracted from the Quality Summary dataset. Only products without errors
(error flag in the MPH set to "0") are used.

5.1 Percentage of products during reporting period with:


At least one measurement with demodulation flag set:	35.0000 %
Reference spectrum computed from DB:	0.00000 %
Reference spectrum with small number of measurements:	0.00000 %
SATU data not used:	0.00000 %

5.2 Plot quality information per product (time dependant)

5.3 Plot quality information per product (world map)

6. Statistics and plot of tangent altitude of the last measurement (DARK & BRIGHT products without errors)

6.1 Statistics on tangent altitude lost:

Statistics	DARK	BRIGHT	TWILIGHT
Mean:	13.713	20.676	11.426
St. deviation:	3.9733	5.7313	0.0000
Maximum:	20.642	29.199	11.426
Minimum:	5.6321	3.6517	11.426
Number of data:	33.000	18.000	1.0000

6.2 Plot for DARK limb products

6.3 Plot for BRIGHT limb products

6.3 Plot for TWILIGHT limb products

7. Star Acquisition and Tracking Unit (SATU)

The Star Acquisition and Tracking Unit (SATU) analyses the position of the tracked star beam collected by
the GOMOS telescope and deflected by the optical beam dispatcher. The main functin of the SATU is to detect
a star, provide its image position to the science data electronics and to help the pointing function to keep
the star image at a fixed position. In tracking mode the SATU data is recorded with a frecuency of 100 Hz.

7.1 SATU 'X' and 'Y' axis plots (dark limb)

SATU CCD 'X' and 'Y' axis plots are provided in order to detect any abnormal behaviour of the tracking system.
For every occultation (color) the plot should remain stable (with some noise) until we are deep in the atmosphere
where big fluctuations are registered due to the refractive effects.

7.2 Statistics on SATU Noise Equivalent Angle (NEA) for DARK (D) and BRIGHT (B) products above 105 kms

The Star Acquisition and Tracking Unit (it is the CCD that tracks the star while it is occulted) Noise Equivalent
Angle consists of the statistical angular variation of the SATU data above the atmosphere.
Statistics (in microradians) above 105 km are computed for every occultation, giving four values per occultation: one in the 'X'
direction and one in the 'Y' direction for dark and bright limbs. A mean value per day in every direction and limb
is calculated and monitored in order to assess instrument performance in terms of star pointing.

7.2.1 SATU NEA Statistics (table)

Statistics	SATU X (D)	SATU Y (D)	SATU X (B)	SATU Y (B)
Mean:	0.18746	0.098699	0.13621	-0.18068
St. deviation:	0.46541	2.9684	0.50666	3.1190
Maximum:	7.0000	12.100	5.1000	11.800
Minimum:	-20.100	-11.900	-4.4000	-12.200
Number of data:	31800.	31800.	16950.	16950.

7.2.2 Trend of daily SATU NEA St. deviation since 1st April 2006 (dark limb)

The long term trend of the SATU 'X' and 'Y' standard deviations should be constant during the whole mission.

The colorbar represents the start tangent altitude (km) of the occultations.

Upper curve: STD of SATU Y axis
Lower curve: STD of SATU X axis
