GOPR prototype versions

Level 1b

Version
Date
Modifications
5.4a
06/01/03
modify the ECMWF filename information in the SPH of the level 1b and limb products
17/01/03
use the start and stop dates of the occultation when calling the CFI interpol instead of start and stop dates of the level 0 product
17/01/03
version freezed
5.4b
30/01/03
modify the computation of flag_mod in the modulation correction routine
14/02/03
modification of the CAL ADFs (update of the wavelength assignment of SPB1 and SPB2)
21/02/03
DC map values are rounded when written in the level 1b product
21/02/03
version freezed
5.4c
27/02/03
modification of the logic to handle dark charge map refresh at orbit level (DSA data is now directly processed by the level 1b processor if available in the level 0 product). No impact on the results.
14/03/03
modifications to allow compatibility with ACRI computational cluster (no modifications of the results)
10/04/03
modification of the CAL ADFs (update of the limb radiometric LUT). The products are affected only if the limb spectra are converted into physical units.
17/03/03
version freezed
5.4d
20/05/03
The maximum number of measurements is set to 509 (instead of 510) in the GOPR prototype.
02/07/03
version freezed
5.4e
11/07/03
Sun zenith angle is computed in the geolocation process. The occultation is now classified into (0) full dark limb condition, (1) bright limb condition and (2) twilight limb condition.
15/07/03
No background correction applied in full dark limb condition. The location of the image of the star spectrum on the CCD array is no more aligned with the CCD lines.
17/07/03
version freezed
5.4f
11/07/03
Sun zenith angle is computed in the geolocation process. The occultation is now classified into (0) full dark limb condition, (1) bright limb condition and (2) twilight limb condition.
21/07/03
The demodulation process is applied only in full dark limb and twilight limb conditions.
