ErrorCode¶
- class lsst.ts.idl.enums.MTRotator.ErrorCode(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)¶
Bases:
IntEnum
Error codes.
The values are:
CONTROLLER_FAULT: The low-level controller went to fault state. Note that the CSC will trigger this if the camera cable wrap is not following closely enough, or if a user issues the
fault
command.CONNECTION_LOST: The CSC lost communication with the low-level controller.
NO_CONFIG: The CSC did not receive configuration from the low-level controller shortly after connecting to it.
Attributes Summary
the denominator of a rational number in lowest terms
the imaginary part of a complex number
the numerator of a rational number in lowest terms
the real part of a complex number
Methods Summary
Return integer ratio.
bit_count
(/)Number of ones in the binary representation of the absolute value of self.
bit_length
(/)Number of bits necessary to represent self in binary.
Returns self, the complex conjugate of any int.
from_bytes
(/, bytes[, byteorder, signed])Return the integer represented by the given array of bytes.
to_bytes
(/[, length, byteorder, signed])Return an array of bytes representing an integer.

Methods Documentation
- as_integer_ratio(/)¶
Return integer ratio.
Return a pair of integers, whose ratio is exactly equal to the original int and with a positive denominator.
>>> (10).as_integer_ratio() (10, 1) >>> (-10).as_integer_ratio() (-10, 1) >>> (0).as_integer_ratio() (0, 1)
- bit_count(/)¶
Number of ones in the binary representation of the absolute value of self.
Also known as the population count.
>>> bin(13) '0b1101' >>> (13).bit_count() 3
- bit_length(/)¶
Number of bits necessary to represent self in binary.
>>> bin(37) '0b100101' >>> (37).bit_length() 6
- conjugate()¶
Returns self, the complex conjugate of any int.
- from_bytes(/, bytes, byteorder='big', *, signed=False)¶
Return the integer represented by the given array of bytes.
- bytes
Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.
- byteorder
The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
- signed
Indicates whether two’s complement is used to represent the integer.
- to_bytes(/, length=1, byteorder='big', *, signed=False)¶
Return an array of bytes representing an integer.
- length
Length of bytes object to use. An OverflowError is raised if the integer is not representable with the given number of bytes. Default is length 1.
- byteorder
The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use `sys.byteorder’ as the byte order value. Default is to use ‘big’.
- signed
Determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised.
