Level 2 products

1. General Info

This report presents the daily analysis on parameters extracted from GOMOS level 1b data (GOM_TRA_1P).
It is intended to monitor some important parameters that will impact the quality of the level 2 products
as the Spectrometers and Photometers CCD Temperatures and Dark Charge, SATU noise equivalent angle...
A list of level 0 products (and content) that have arrived during the actual month to the PCF is also given.

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 All products used the DSA observation for the 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:	28.5714 %
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:	12.572	16.945	14.510
St. deviation:	5.0133	5.4834	3.1267
Maximum:	20.316	22.665	18.989
Minimum:	4.9229	6.6590	8.9476
Number of data:	20.000	17.000	12.000

6.2 Plot for DARK limb products

6.3 Plot for BRIGHT limb products

6.3 Plot for TWILIGHT limb products

7. 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 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.

Statistics	SATU X (D)	SATU Y (D)	SATU X (B)	SATU Y (B)
Mean:	1462.4	1446.3	1461.4	1447.6
St. deviation:	4.3304	7.1809	6.2140	8.6912
Maximum:	1506.0	1507.0	1505.0	1515.0
Minimum:	1427.0	1386.0	1440.0	1416.0
Number of data:	25350.	25350.	20400.	20400.

8. Auxiliary Data Files used for the production reported in section 2.2

The number reported in the third column indicates since which file (see list in section 2.2) the corresponding
auxiliary file has been used. The fourth column is the date of those product files.
