Calculate the rate of charge accumulation when the sensor is not illuminated.

Parameters:

temperature (None | Quantity | AbstractScalar) – The temperature of the sensor. If None, the value of temperature is used.

Examples

to_string(prefix=None)

Public-facing version of the __repr__ method that allows for defining a prefix string, which can be used to calculate how much whitespace to add to the beginning of each line of the result.

Parameters:

prefix (None | str) – an optional string, the length of which is used to calculate how much whitespace to add to the result.

Return type:

str

azimuth: Quantity | AbstractScalar = <Quantity 0. deg>

The angle that the detector has been rotated about the axis of symmetry.

cte: u.Quantity = <Quantity 99.9995 %>

The charge transfer efficiency of the sensor.

distance_radial: Quantity | AbstractScalar = <Quantity 0. mm>

The distance between the axis of symmetry and the center of the detector.

family: str = 'CCD230-42'

The model number or product family of this sensor.

grade: None | str = None

The quality of the device.

Grade 0 is the best possible and Grade 5 is the worst possible.

manufacturer: str = 'Teledyne/e2v'

The company which produced the sensor.

num_blank: int = 50

The number of blank columns at the start of each row.

num_overscan: int = 2

The number of overscan columns at the end of each row.

property num_pixel: Cartesian2dVectorArray

The number of pixels along the horizontal and vertical axes.

property num_pixel_active

The number of pixels that are used to detect light.

If readout_mode is "full-frame", then this is the same as num_pixel. If readout_mode is "transfer", then the vertical component of num_pixel is divided by 2 since half of the sensor is now used for charge storage.

num_pixel_x: int = 2048

The number of pixels along the horizontal axis of the CCD sensor.

num_pixel_y: int = 2064

The number of pixels along the vertical axis of the CCD sensor.

num_tap_x: ClassVar[int] = 2

The number of taps along the long axis of the CCD sensor.

num_tap_y: ClassVar[int] = 2

The number of taps along the short axis of the CCD sensor.

pitch: Quantity | AbstractScalar = <Quantity 0. deg>

The pitch angle of this sensor.

position_image: Quantity | AbstractCartesian2dVectorArray = <Quantity 0. mm>

The position of the center of the FOV on the sensor for the target wavelength.

readout_mode: Literal['full-frame', 'transfer'] = 'transfer'

The frame readout mode of the sensor.

Either the entire sensor is read at the same time ("full-frame"), or half of the sensor is used for storage ("transfer").

readout_noise: u.Quantity = <Quantity 4. electron>
