## detectors
| Name | Description | Ang. acceptance<br>HxV (deg) | Offset | Max tth | Det Num | Norm Det Num (d/I<sub>0</sub>) |
|------|-------------|------------------------------|--------|---------|---------|--------------------------------|
| mesh (I<sub>0</sub>) | Au mesh | 1 cm<sup>2</sup> | n/a | n/a | D31 | n/a |

```python
tthdet.set('d3',move=True) # select a given detector (d3,d4, or mcp); move = True/False
tthdet.get() # returns the name of the current detector
mvtth(90) # moves the selected detector
scaler_cts(1) # set counting time to 1s
d3/d4
d3.setgain(2,'pA') # set gain for d3 to 2 pA
d3.get() # returns the current with background subtraction in Amps
d3.get_all() # returns all the current settings
```
See below for a complete list of signals recorded during a scan and their corresponding [detector number](#detector-number) (Det Num).
## energy
```python
energy(932) # set undulator (ID), mono, apertures and mirror
polarization('V') # Turns the ID off and then sets the polarization:
# 'RCP', 'LCP', 'H', 'V'
# **need to set energy after a mode change!**
mvmono(500) # change mono
slit(100) # set energy resolving slits (and vertical beam size)
m3r_align() # realign mirror
scanmono # scan mono only and is a linear (constant step size)
scanXAS(hv_list_of_lists) # scan mono with variable step size; ID_tracking = True/False
hv_list_of_lists = [[445,455,0.5],[455,468,0.1],[468,475,0.5],[475,480,1]]
