SegmentSimulator¶
- class lsst.cp.pipe.SegmentSimulator(imarr, prescan_width, output_amplifier, cti=0.0, traps=None)¶
Bases:
object
Controls the creation of simulated segment images.
- Parameters:
- imarr
np.ndarray
(nx, ny) Image data array.
- prescan_width
int
Number of serial prescan columns.
- output_amplifier
lsst.cp.pipe.FloatingOutputAmplifier
An object holding the gain, read noise, and global_offset.
- cti
float
Global CTI value.
- traps
list
[lsst.ip.isr.SerialTrap
] Serial traps to simulate.
- imarr
Methods Summary
add_trap
(serial_trap)Add a trap to the serial register.
ramp_exp
(signal_list)Simulate an image with varying flux illumination per row.
readout
([serial_overscan_width, ...])Simulate serial readout of the segment image.
Methods Documentation
- add_trap(serial_trap)¶
Add a trap to the serial register.
- Parameters:
- serial_trap
lsst.ip.isr.SerialTrap
The trap to add.
- serial_trap
- ramp_exp(signal_list)¶
Simulate an image with varying flux illumination per row.
This method simulates a segment image where the signal level increases along the horizontal direction, according to the provided list of signal levels.
- readout(serial_overscan_width=10, parallel_overscan_width=0)¶
Simulate serial readout of the segment image.
This method performs the serial readout of a segment image given the appropriate SerialRegister object and the properties of the ReadoutAmplifier. Additional arguments can be provided to account for the number of desired overscan transfers. The result is a simulated final segment image, in ADU.
