v1.0.0.0 2018-11-14 - Created PDS4 LDD based on PDS3 Catalog file content. The Dawn class is the container for Dawn mission-specific metadata elements. The Dawn "fc" class is the container for Dawn Framing Camera (FC) specific metadata elements. The Dawn "vir" class is the container for Dawn Visual and Infrared Spectrometer (VIR) specific metadata elements. This section contains the simpleTypes that provide more constraints than those at the base data type level. The simpleTypes defined here build on the base data types. This is another component of the common dictionary and therefore falls within the common namespace. Same as global keyword START_TIME; allows one label to specify both YYYY-MM-DD and YYYY-DDD without using a list. Same as global keyword STOP_TIME; allows one label to specify both YYYY-MM-DD and YYYY-DDD without using a list. Callamp switch on delay measured in microseconds after START_TIME. Callamp can be switched on before (less than 193000 µs), at (= 193000 µs), or after (greater than 193000 µs) begin of exposure. The callamp can be run at various duty cycles between 0.0 % and 100.0 % by using only every other pulse of the callamp frequency to trigger the callamp. DAWN_CALLAMP_DUTY = CALLAMP_FREQUENCY / Value * 100 % Example: Value = 1.0 : DAWN_CALLAMP_DUTY = 100 % Value = 2.5 : DAWN_CALLAMP_DUTY = 40 % This calculation is done internally in the camera, the user commands the requensted duty cycle in percentage. OFF = callamp set to disabled ON = callamp set to enabled The callamp frequency is determined by the internal 24 MHz clock and an integer divisor. CALLAMP_FREQUENCY = 24 MHz / Value The standard callamp frequency is 100 kHz (24MHz / 240). Callamp strobe time is measured in microseconds after callamp switch on. callamp switch off time = START_TIME + DAWN_CALLAMP_DELAY_TIME + DAWN_CALLAMP_STROBE_TIME This keyword was used during ground tests to describe the test environment. This keyword describes the priority of the acquired image and thus how it was handled on board. Op-Nav = The image is processed with highest priority and streamed into VR10 of the s/c. Science 1 = The image is processed with high priority and streamed into VR8 of the s/c. Science 2 = The image is processed with mid priority and streamed into VR8 of the s/c. Science 3 = The image is processed with low priority and streamed into VR8 of the s/c. Science 4 = The image is processed with least priority and streamed into VR8 of the s/c. Both DPUs for FC1 and FC2 have the same DPU ID because they are identical. Current version of the FC onboard software OFF = FEE is disabled, images cannot be acquired ON = FEE is enabled, images can be acquired 017.10.10 = FEE ID of FC1 (FS1) 017.09.09 = FEE ID of FC2 (FM2) 063.15.15 indicates that the FEE is off or busy and cannot transmit its ID. FILTER_NUMBER = (((64 + 4 + encoderOnClearFilter - FILTER_ENCODER) / 8) MOD 8) + 1 encoderOnClearFilter is a hardware-dependent constant filterEncoder is the current readout of the encoder filterNumber return a value in the range [1..8]. All the operation are integer operations, MOD represents modulo and / is the integer division. The subtraction is negative (F1 - Fx) because the encoder value decreases with increasing filter number. This keyword defines the units of FRAME_PARAMETER that define the individual frame parameters of an instrument that transfers single frames to the mass memory of the spacecraft or the instrument. The FRAME_PARAMETER element is also accompanied by the element FRAME_PARAMETER_DESC, e.g. FRAME_PARAMETER_DESC = ('EXPOSURE_DURATION', 'FRAME_SUMMING', 'EXTERNAL_REPETITION_TIME', 'EXTERNAL DARK_ACQUISITION_RATE') CLOSED = Front Door, covering the aperture, is closed. DOOR = Front Door is open. The Front Door is closed if FRONT_DOOR_ENCODER shows the nominal value +/- 1 and otherwise is open. Fail Safe Actuator: OFF = The Fail Safe Actuator for the Front Door is disabled. ON = The Fail Safe Actuator for the Front Door is enabled. FSA_SHOOT_FLAG can be switched ON now. Fail Safe Actuator: OFF = The Fail Safe Actuator for the Front Door is switched off. ON = The Fail Safe Actuator for the Front Door is switched on. Camera Head Heater: OFF = The CH heater (HEATER0) is switched on. ON = The CH heater (HEATER0) is switched off. The heater produces 4.4 W (5.6 Ohm at +5 V) Baffle Heater: OFF = The Baffle heater (HEATER1) is switched on. ON = The Baffle heater (HEATER1) is switched off. The heater produces 1.0 W (26 Ohm at +5 V) Name: C12FEE Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: 0.02 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_12 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 50 mA Lower limit yellow: 60 mA Upper limit yellow: 100 mA Upper limit red: 200 mA Name: C16V15 Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: 0.009 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_16 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 20 mA Lower limit yellow: 30 mA Upper limit yellow: 60 mA Upper limit red: 100 mA Name: C28M Location: PCU H/K Sensor: MAIN +28V Current Monitor Sensor Type: Current Sensor Gain: 0.0016 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_28 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 200 mA Lower limit yellow: 250 mA Upper limit yellow: 1200 mA Upper limit red: 1400 mA Name: C2.5AN Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: 0.15 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_2_5 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 250 mA Lower limit yellow: 300 mA Upper limit yellow: 900 mA Upper limit red: 1000 mA Name: C3.3AN Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: 0.15 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_3_3 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 100 mA Lower limit yellow: 170 mA Upper limit yellow: 850 mA Upper limit red: 1400 mA Name: C5FEE Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: 0.05 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_2_5 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 100 mA Lower limit yellow: 250 mA Upper limit yellow: 350 mA Upper limit red: 400 mA Name: C5AN Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: 0.2 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_5_ANALOG = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: 75 mA Lower limit yellow: 100 mA Upper limit yellow: 1150 mA Upper limit red: 1300 mA Name: C-5FEE Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: -0.015 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_M5 = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: -200 mA Lower limit yellow: -120 mA Upper limit yellow: -60 mA Upper limit red: -30 mA Name: C-5AN Location: PCU H/K Sensor: PCU Current Monitor Sensor Type: Current Sensor Gain: -0.015 Offset: 0 Sensor Offset FC1: 0 Sensor Offset FC2: 0 I_M5_ANALOG = DN * Gain + Offset + Sensor Offset [mA] Lower limit red: -100 mA Lower limit yellow: -60 mA Upper limit yellow: -20 mA Upper limit red: -10 mA This keyword describes the mode of image acquisition.
