1. Login on Sami with username archeops and the usual passwd. You are then in the Home directory 2. From a terminal window type: emacs todo_NameOfProcedure.pro & 3. This file to have examples of input parameters of the real time analyses to use
- General Info:
- all the products of the real time data analysis (.png, .fits, .save) are stored in this folder ………..;
- the parameter scan_num (number of scan) is an integer
- the parameter day (date of the scan) is a string as 'yearmonthday' (ex: '20121120')
- Preliminary actions:
- start idl
- POINTING PROCEDURE:
Determine pointing offset by making 4 subscans (see pointing Pako procedure on …….).
- Open the IDL script RealTime/todo_cross.pro
- execute line X1 updating scan_num and day parameters.
- execute 'cross, scan_num, day, offsets, info=info'
……………………………
- execute print,offset
offset returns the value of the RELATIVE offset for the two arrays wrt previous value set in Pako. The value obtained from 1mm array has to be considered as priority.
- FOCUS PROCEDURE
The procedure intends to maximize the power on one reference pixel (where the considered source is centered) when the position of the secondary mirror is changed by X steps (see Pako procedure on …..).
- Edit the IDL script RealTime/todo_focus.pro
- execute line X1 updating scan_num and day parameters.
- execute 'focus, scan_num, day, z_final, info=info'
the procedure produces 4 plots, 2 for each array. Two plots, one for 2mm array and the other for 1mm array, show the TOD of the procedure. (and the fraction of the plateau chosen for the analysis (in green). Plots IDL33 (2mm array) and IDL35 (1mm array) show the total power (in Hertz!) versus the position of the secondary, for reference pixel (top right in red) and for nearby pixels (9). The best position is fitted with a second order polynomial.
- execute print, z_final
z_final returns the values of the ABSOLUTE best position of the secondary mirror for the two arrays (z_final(0)=best pos 2mm - z_final(1)=best pos 1mm). The value obtained from 1mm array has to be considered as priority.
- SELECT KIDS PROCEDURE
This procedure computes individual maps to determine the kids parameters that can be upgraded in otf_geometry. This procedure should be run only once at the beginning of the campaign.
- Open the IDL script RealTime/todo_x.pro
- execute from line X1 to line X2
- execute 'select_kids, scan_num, day, info=info'
- OTF GEOMETRY PROCEDURE
- Open the IDL script RealTime/todo_x.pro
- execute from line X1 to line X2
- execute 'otf_geometry, scan_num, day, info=info'
