cdfp_rdlists
Last updated: Apr18,2020

Extract the floating point RA,DEC values from a cdfp file and produce 3 ASCII files:

 

  list.RA_DEC_hd   = Ra,Dec in unist of hours and degrees
  list.RA_DEC_dd   = Ra,Dec in unist of degrees and degrees 
  list.RA_DEC_sex  = Ra,Dec in sexigecimal format 

% cdfp_rdlists.sh --help   

Usage: cdfp_rdists.sh a.cdfp 
arg1 - name of input cdfp file
Additional options: 
     -v = print verbose comments 
 --help = view a help document

Although very simple, this turns out to be very useful for writing scripts involving cdfp files. Here is a full example:

 

% cat aps1.cdfp  
Ra_hrs,Dec_deg,Xcent,Ycent,isomag30,NumPix,                                     
  19.740600586  26.221525192   737.840   209.030    12.182  2081.000
  19.739345551  26.207641602   472.520    90.990    14.993   468.000

  19.738698959  26.235244751   458.890   475.300    16.337   289.000

% cdfp_rdlists.sh aps1.cdfp 

%  cat list.RA_DEC_hd 
  19.740600586   26.221525192

  19.739686966   26.216396332
  19.738698959   26.235244751

% cat list.RA_DEC_dd 
   296.10900878906     26.22152519226
   296.09017944336     26.20764160156

   296.08047485352     26.23524475098

%  cat list.RA_DEC_sex 
19:44:26.1621 +26:13:17.491
19:44:21.6440 +26:12:27.510
19:44:12.1614 +26:14:59.293
19:44:22.8731 +26:12:59.027
19:44:19.3163 +26:14:06.881

We so often have need of using one of these three position formats, and it is very easy to paste and awk these files to creat a variety of desired output files in a script.
