class lsst.ts.mtdome.ResponseCode(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)¶

Bases: IntEnum

Response codes.

The codes mean

0, “OK”, “Command received correctly and is being executed.”

1, Not used.

2, “Unsupported”, “A command was sent that is not supported by the lower level component, for instance park is sent to LCS or ‘mooveAz’ instead of ‘moveAz’ to AMCS.”

3, “Incorrect parameter(s)”, “The command that was sent is supported by the lower level component but the parameters for the command are incorrect. This can mean not enough parameters, too many parameters or one or more parameters with the wrong name.”

4, “Incorrect source”, “The current command source is not valid, e.g. a remote command arrives while the system is operated in local mode, like the push buttons for the Aperture Shutters.”

5, “Incorrect state”, “The current command cannot be executed in current state, e.g. moveAz when the AMCS is in fault state.”

6, “Rotating part did not receive”, “It was not possible to forward the command to the rotating part.”

7, “Rotating part did not reply”, “The command was sent to the rotating part, but it did not send a reply before a timeout.”

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.
