This note explains how to download and run the NIRSPEC Echelle Format Simulator (EFS) as a planning tool at a remote workstation. The simulator is an IDL application that requires the following:

1. IDL v5.02 or higher.
2. The EFS is written for 24-bit enabled color displays, so use of such a display is recommended if possible. On 8-bit displays, the color reproduction is not expected to be good.

Installation

1. Download nirspec_simulate_tar.Z
2. The installation requires about 2.2 Mb of disk space. Unpack the files with the command:

     zcat nirspec_simulate.tar.Z | tar xvf -
   

   The following directory structure is created:

   hanakapiai{tbida}7: ls nirspec_simulate
   
   README_simulate			plot_filter.pro
   bad.lst				read_data.pro
   cw_toggle.pro			read_lines.pro
   data/				setups/
   help/				simstartup.pro
   nirspec_sefs.pro		simstartup_ao.pro
   nirspec_sefs.pro.28jan00	test.lst
   ns_params.pro			user.lst
   ns_params_ao.pro		user_lines.pro
   
   

Running the Simulator

1. The simulator can either be run in batch mode, by typing:

     idl simstartup
   

   or, at the IDL prompt, as

     IDL> @simstartup
   

2. To run the simulator in AO mode, type:

     idl simstartup_ao
   

   or,

     IDL> @simstartup_ao
   

   It is very important that setup files that are used real-time at Keck correspond to the mode in current use, non-AO or AO. In other words, loading an AO-mode script into the real-time EFSgui running in non-AO mode may have undesirable consequences, such as potentially moving a filter wheel that should remain fixed.

3. The setups subdirectory is provided to store user scripts written by the EFS, which emulates the directory structure at Keck HQ.

4. The simulator includes a 'Help/User Manual' selection which launches a local copy of netscape to view the documentation. Much of the same documentation resides in the NIRSPEC User's Manual, available on line from the NIRSPEC/WMKO home page:
