User Accounts for SpeX

spex – host the spex web site. Used by support scientist to provide documentation on spex to observers.

Bigdog – user account to run the bigdog software. Bigdog is the spectrograph camera software. It normally runs inside the VNC stefan:1

Guidedog – user account to run the guidedog software. Guidedog is the imager/guider camera software. It normally runs inside the VNC stefan:2

Ldog – user account to run the ldog software. Ldog is the instrument controller (motor, temperature controlers, etc).ldog create it own VNC server, ldog:16000, where the ldog_ic application runs.

s2 – user account for spex programmer. Source code, development documentation is store here. Also has the sim/ directory to run spex in simulation mode.

The original spex (sparc/vme/redstar) was build from 1994-2000, and used at the IRTF from May 2000 to Aug 31, 2013. This Spex 1.0 bigdog, guidedog user accounts were rename as oldbigdog, oldguidedog.spex has the old 1.0 source code In /home/src/spex/. There was no ldog account, littledog was an embedded PC running inside of coolracks.

Bigdog Account

The bigdog account runs the spectragraph software. The user bigdog should login to the bigdog computer.Important directies in bigdog:

/home/bigdog/

|-- current/ - The current version of bigdog.

|-- old/ - order binaries are archived here.

|-- dev/ - A test or development binaries.

|-- macro/ - bigdog macros.

|-- include/ = include files. (so we con’t use /usr/local).

|-- lib/ - lib for bigdog (so we don’t used /usr/local).

|-- src/ - source dirctory. Should be soft lins to /home/s2.

|-- tools/ - contains iarc’s dsp compiler.

|-- bin/ - user scripts, like startic, etc.

GuideDog Account

The guidedog account runs the imager/guider software. The user guidedog should use the guidedog computer.Guidedog is similar to bigdog. It has the same directories with the same purposes.

ldog Account

The ldog (littledog) account runs the ldog_ic software on the ldog computer. Important directories in the account are:

/home/ldog/






s2 Account

The s2 account is used by the spex program for development and testing. This account has the source code, documentation, and the sim/ binaries..

Important directories in the account are:

/home/s2/

the position to 0.

Position the stage OUT Or IN using the step position in the table.

When the motor is idle, the power to the stepper driver should be OFF.

The Dichroic Wheel is also know as DIT.

The DIT is a detent wheel. The detents provide reproducible positioning for

each position. An HE sensor senses the home and indetent magnets. A

single magnet defines the home position. A each detent, a magnets with

reverse polarity are installed. Two comparator circuit are used to provide a

“home” and “indetent” signal..

To initialize we drive the wheel forward until the Forward limit is triggered.

This defines the home position.

To move to a detented position, we use the (default) detent_center() or

detent_moveto() algorithms.

The Rotator is a continuous wheel Mechanism.

Methods for describing the rotator’s position.

Motor Steps – The rotator is controlled using a stepper motor. The mechanism has a step range of 0 to 1,440,000.

Rotator Angle – The rotator angle is simple mapping of degrees (0 to 360) to the motor steps (0 to 1,440,000).

Position Angle – The position angle describes the orientation of the slit to the sky image. 0 degrees, the slit is vertical (North on Top). Positive

angles rotator the slit clockwise. Negative angles rotate the slit counter-clockwise.

This diagram illustrates the relationship between theses position.

The Slit Wheel is also know as SLIT.

The SLIT is a detent wheel. The detents provide reproducible positioning for

each position. An HE sensor senses the home and indetent magnets. A

single magnet defines the home position. A each detent, a magnets with

reverse polarity are installed. Two comparator circuit are used to provide a

“home” and “indetent” signal..



To move to a detented position, we use the (default) detent_cente() or

The Guider Filter Wheel, GFLT, is a 15 position detent wheel. The detents

provide reproducible positioning for each position. An HE sensor senses the

home and indetent magnets. A single magnet defines the home position. At

each detent, a magnets with reverse polarity is installed. Two comparator

circuit are used to provide a “home” and “indetent” signal..



To move to a detented position, we use the detent_moveto() algorithms.

There are 6500 steps per motor revolution.1 revolution of the axis = 50 microns of linear travel.

Several Nth degree polynomial equations are used to convert between HE Sensors voltage output and the motor position counts. The y = f( x ) represents a Nth degree polynomial fit.

Data and fit documented in src/spex/ldog/afoc_fit/

The equations are:

y = a + xb + x2c + x
