SIC variable corresponding to MIRA's data structure

 

var prim r [w]	retrieves primary header as SIC variables for
	reading (default) or writing.
var scan r [w]	same for the scan header and table sections
var febe r [w]	frontend-backend header and table sections
var array r [w]	arraydata headers and table sections
var data r [w]	data headers and table sections
var mon r [w]	monitoring headers and table sections
var gains r [w]	MIRA variables
var choice r [w]	search options for MIRA command find
var reduce r [w]	MIRA internal flags for calibration history

 


Here is a listing of the corresponding SIC variables. The array dimensions are specified by the following parameters:

$n_{\rm fb}$	number of frontend-backend combinations
$n_{\rm pix}$	number of pixels
$n_{\rm bd}$	number of basebands
$n_{\rm cpb}$	number of spectral channels per baseband
$n_{\rm chan}$	number of spectral channels (concatenated basebands)
$n_{\rm off}$	number of off positions from catalogue position
$n_{\rm rec}$	number of records (= backend data)
$n_{\rm ph}$	number of phases (e.g. 2 = on, off)
$n_{\rm subsc}$	number of subscans
$n_{\rm subr}$	number of subreflector monitor points
$n_{\rm slow}$	number of antenna monitor points (slow rate)
$n_{\rm fast}$	number of antenna monitor points (fast rate)

 


Variable types are denoted as S (structure), I (integer), R (real, single precision), D (real, double precision), C (character string) and L (logical).


Caveats: (1) Neither the MIRA data structures nor the corresponding SIC structures are exactly mapped from the MBFITS V1.54 file definition. However, I tried to keep them as close as possible.    (2) Not all of the following items are already copied from the IMBFITS file to SIC variables (even if the SIC variable is declared).
