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.

3. Plot of GOMOS spectrometers and photometers temperatures from level 1b data

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:

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.
