The following files contain a signal, although calibrated versions are not available in the archive. They consist in cruise tests, in observations at the limb of Mars or on Phobos during "dark sky" calibration sequences, and in an observing session in nominal mode when the spacecraft was not stabilized.
Spinning session
Labels are combined in file LIM_EDT.LBL.
File name | Origin | Observing mode | Gain | Integration time | Viewing direction | Focal plane temperature | Window size |
SPINEVEN.EDT SPINODD.EDT |
Main session in Mars2202.dat 02:28:03,625 to 02:55:07,375 |
Mars mode 0 | 2 | 0,5 s | Starting mirror position = 228 ; step = 1 | 72,3°C | 121 x 25 |
3025 spectra acquired on Mars and on the sky, with two limb crossings (at 2:35 and 2:48). The observed area is unknown (spacecraft’s spinning axis and rotation speed are unknown), but the instrument would have observed the Elysium area if stabilized. This session could be calibrated, with no correction for misregistration effect, and applying the second level temperature correction similar to that in Arabia. |
Cruise tests
Labels are combined in file CRU_EDT.LBL.
File name | Origin | Observing mode | Gain | Integration time | Viewing direction | Focal plane temperature | Window size |
CRU1EVEN.EDT CRU1ODD.EDT |
From Jantest.dat 16:53:31,0 to 16:53:32,0 |
Mars flyby mode 0 7 samples/line. |
1 | 0,125 s | Starting mirror position = 254 ; step = 1 | -72°C | 9 x 1 |
9 spectra acquired during a technical cruise test. Acquisition begins earlier but previous spectra contain no information ; the first two spectra of this set are null also. Spectra are written in sequence, as if there was one line of 9 samples. The signal measured is probably the Sun’s reflection on the spacecraft tank. | |||||||
CRU2EVEN.EDT CRU2ODD.EDT |
From Jantest.dat 16:53:36,0 to 17:00:07,5. |
Mars global mode 3 50 samples/line. |
1 | 1 s | Starting mirror position = 156 ; step = 4 | -72°C | 7 x 49 |
343 spectra in mode, the last ones are zeros. The signal measured is probably the Sun’s reflection on a tank. This session is performed as part of a technical cruise test. |
Limb observations
Labels are combined in file LIM_EDT.LBL.
