= Old HPF control procedures =

you should probably be using the wrappers on the [wiki:HetProcedures/RA/hpf main hpf page].

== Setup for not available modes ==


=== HPF HE mode === #heoffsets

WARNING: these have not been measured/verified since about 2019!! Do not use without re-verifying!!

 * {{{ syscmd -T  'Guider1_offset_probe (dx_ang=5,dy_ang=4)' }}}
 * {{{ syscmd -T 'Guider1_offset_fiducial (dx_asec=-5.9,dy_asec=-9.6,compensate="true")' }}}

OR

 * {{{ syscmd -T  'Guider2_offset_probe (dx_ang=5,dy_ang=4)' }}}
 * {{{ syscmd -T 'Guider2_offset_fiducial (dx_asec=-5.9,dy_asec=-9.6,compensate="true")' }}}



== Instrument Control ==



To get to the HPF machine:
ssh -X hpf@192.168.66.125 

We communicate with HPF via screens: 
(HPFpython) [hpf@hpfserver ~]$ screen -rd pyhxrg

Run python

Data is stored in /home/hpf/HPFData/LinuxGigE/YYYYMMDD/hpf

Scripts for changing the instrument settings are located in /home/hpf/Scripts/InstConfig

=== Upon startup ===

{{{
cd /home/hpf/HPFics/hxrg/pyhxrg
routine to power up:   hxrg_test.py

Cut and paste the first ~20 or so lines of hxrg_test.py into operation window:
-----------------------------------------------
from hxrg_initialize import Initialize
from hxrg_configureasic import ConfigureAsic
from hxrg_startexposure import StartExposure
from hxrg_powerdown import PowerDown

import hxrg_core

import os, glob

hxrg = hxrg_core.HxRG()

hxrg.obsnum=1
hxrg.object = 'Eng'
Initialize(hxrg)
ConfigureAsic(hxrg, biasfile='HxRG_SCA17083.bias')
hxrg.imunwrap = True
hxrg.diagnosticfits = True
hxrg.ConfigureUpTheRamp(nreads=10,nramps=1,nresets=2)
hxrg.SetOutputChannels(4)
hxrg.ReconfigureAsic()
}}}

=== Cal sets ===

{{{
hpf_thar_on.sh                              # let lamp warm up 
hpf_setup_thar_he.sh                        # move mechanical parts 
>>> hxrg.object = 'Uranium Slave'
>>> hxrg.obsnum += 1
>>> hxrg.ConfigureUpTheRamp(nreads=10)      # number of images per ramp 
>>> hxrg.ReconfigureAsic()                  # apply the changes 
>>> StartExposure(hxrg)
}}}

===  On sky observing ===

{{{
>>> hxrg.object = 'GJ_87'                   # record name 
>>> hxrg.obsnum += 1                        # increment counter 
>>> hxrg.ConfigureUpTheRamp(nreads=20)      # number of images per ramp 
>>> hxrg.ReconfigureAsic()                  # apply the changes 
>>> StartExposure(hxrg)
}}}

A short cut we used was

{{{ hxrg.obsnum += 1; StartExposure(hxrg); beep() }}}

A more comprehensive shortcut 

{{{ 
SetNewObs(ObjectName,30)          # set nreads=30 for target ObjectName
TakeNewExposure(3,ObjectName)     # will take 3 exposures of target ObjectName 
}}}

Changing filters on any window on hpf

{{{
tims calib tlfltrwhl1:pos:2      # move filter wheel 
tims calib tlfltrwhl1:pos?       # query filter wheel 
}}}

Opening or closing the laser frequency comb (lfc) from the scripts directory /home/hpf/Scripts/InstConfig

{{{
./hpf_lfc_close.sh
./hpf_lfc_open.sh
}}}

To abort an exposure
guider1setup
{{{
cntrl-C
hxrg.AbortExposure() 
hxrg.ReconfigureAsic() 
hxrg.ReconfigureAsic() 
}}}

=== Shutdown ===

{{{
cntrl-a-d
./hpf_all_off.sh 
}}}
