Optical Monitor OM1 Simulators

om1_sim

This is the main simulator. It is based on previous simulators and tried to calculate events real-time and output them through a PC ISA card to the DPU.

setenv XMMOMMSSLSIM .../data      wherever the data is
cd .../fields

The source file e.g., EG_And.dat, has the RA/Dec as the first line then each line consists of:

1 means star or ellipse, 0 means background, 2 means galaxy
offset (arcsec) from centre
offset (arcsec) from centre
magV
scale
ellipse maj
ellipse min
ellipse angle
source type (as numbered in tab/general.tab; the first being 0)

Here are the answers to the questions:

multiple star fields? n
field file EG_And.dat
variable source y
data file variable.dat

fast simulator

To get the fast fast simulator:

logon to mssls7
get ~jpdm/xmm/fast/fast_check.c
get ~jpdm/xmm/fast/sourcecat_6.dat

and put them in a directory somewhere. Compile using

gcc -O -o fast_check fast_check.c

To run the fast fast simulator:

io_lx fast_check

fast_sim will say something like this with the responses in bold. The "1028 1028" is the position of the bfast source.

2 msslge:~jpdm/xmm/fast% io_lx ./fast_check
user_id: 208
********** Writing to hardware ****************
Input sourcecat_*.dat file : sourcecat_6.dat
Input source 1 for fast mode : countrate (c/s) : 100
                                    Xpos, Ypos : 1028 1028
Input detector windows file (<CR> for whole detector) :       <CR>
Number of sources 349
Read out time is 0.010948 
Total count rate : 19762.766470
Input running time : 100000000
Aquisition mode is 0

And it is running waiting for Choose Guide Stars.

Open an archive
Run cgs and anything necessary for the exposure as far as <exp
Close the archive
^c the fast_check program
Run split_archive archive_name
Run win archive_name

Grab the output from the win program "Detector windows" section from line 1 downwards, e.g.:

 1    512    528    512    512        0      0    976 4194304    496
 2    512   1040    512    464        0      0    976 4194816    496

and put it in a file called anything, e.g.: det.win

Run fast_check again
This time when it asks for "Input detector windows file" don't type Return, put in this filename, e.g., det.win
Then run a script with multiple alternate tc_set_exp_no expid and <exp commands in it.

The output should look like this:

2 msslge:~jpdm/xmm/fast% io_lx ./fast_check
user_id: 208
********** Writing to hardware ****************
Input sourcecat_*.dat file : sourcecat_6.dat
Input source 1 for fast mode : countrate (c/s) : 100
                                    Xpos, Ypos : 1028 1028    
Input detector windows file ( for whole detector) : /home/pjs1/det.win
Number of sources 93
Read out time is 0.006813 
Total count rate : 19546.454810
Input running time : 1000000000
Aquisition mode is 2

then the fast sim will keep producing events for a long time.

Restarting the sim

To change fields, control-C the VxWorks script during the last taskDelay of "exp" and wait 1000 s. Then control-C the simulator and run it again with a different field.

The script
