Routine Descriptions

WSTBINDATA - BIN DATA TO THE REQUESTED TIME STEP

[Next Routine] [List of Routines]
NAME: 
wstbindata - bin data to the requested time step

                 hrdat=hrdat,degdat=degdat,jddat=jddat,hist=hist)
ARGS:
 yinp[n]: float/double data to process
 xinp[n]: double   x value for each y sample
KEYWORDS:
 binsize : double  for histogram (see defaults below
 jddat   :         if set then assumme xdat is jd dates.
                   round to full ast days. this is the default
                   if hrdat,degdat is not supplied
                   Def binsize=15/1440. (15 minutes)
 hrdat   :         if set then xdat is in hours
                   def binsize is .1 hours
 degdat  :         if set then xdat is in degrees.
                   def binsize=1 deg.
              
RETURNS:
  nbins: long   number of bins in returned datahistogram
Davg[nbins]:double average the points in each bin
Dpk[nbins] :double take peak value from each bin
Djd[nbins] :double xvalue value for center of each bin
hist[nbins]   :double return the histogram
               
DESCRIPTION:
   bin the input data using the xinp array. The default
binwidth is:
 jd data : 15/1440 (15 minutes5 minutes).
 hr data : .1 hours
 degdata:  1 deg
 You can change the binwidth with the binsize=keyword.
width with the tmStep= keyword.
	The prgoram returns the following binned data:
 Bavg[nbins]: averag data in each bin
 Bpk [nbins]: peak data in each bin
 Bx[nbins]  : x values for center of each bin

SYNTAX: jd=wstdatetojd(datestr)
ARGS:
   datestr: string  format "mm/dd/yy hh:mm:ss" ast
               
DESCRIPTION:
   Convert datestr from weather station to julday.

(See /pkg/rsi/local/libao/phil/wst/wstdatetojd.pro)


WSTGETARCHIVE - RESTORE ALL OR PART OF CALIBRATION ARCHIVE

[Previous Routine] [Next Routine] [List of Routines]
NAME:
wstgetarchive - restore all or part of calibration archive
SYNTAX: count=wstgetarchive(yymmdd1,yymmdd2,ball,ndays=ndays,dir=dir,$
                            maxDays=maxDays)
ARGS: 
yymmdd1  : long    year,month,day of first day to get (ast)
yymmdd2  : long    year,month,day of last  day to get (ast)
KEYWORDS:
    ndays: long    number of days to return. If supplied then
                   ignore yymmdd2. 
      dir: string  If provided, then this is the path to 
                         acces the archive save files. The default 
                         is:/share/megs2_u1/wst/ .
   maxDays: long   by default the program will limit you to
                   about 366 days (this is about 240Mbytes). If 
                   you want more data, than set maxdays to the
                   maximum allowable value (be sure your computer
                   has enough memory).
RETURNS:
   ball[count]: {wst}     number of samples returned
DESCRIPTION:
   This routine will input weather station data stored in the
idl archive. This archive is updated at the end of each month
from the online file. 
You specify the start and end dates of the data to extract. 

	A single month will consist of about 20Mbytes of data.

EXAMPLES

;get all data for jan14
 nrecs=wstgetarchive(140101,140131,ball)

(See /pkg/rsi/local/libao/phil/wst/wstgetarchive.pro)

DESCRIPTION:
   load wst structure from ascii input line

(See /pkg/rsi/local/libao/phil/wst/wstldrec.pro)


WSTPLOTMON - MONTHLY WEATHER STATION PLOTS

ARGS:
yymm : int  year,month to plot
KEYWORDS:
wait :   if set the wait for keyboard input between plots
usebar:  if set then user passes data in via bar= keyword.
         program will not read it in
RETURNS:
npnts: long < 0 --> error
            > 0  number of points in month
bar[npnts]:{} if usebar is not set then the input data will be
              passed back in bar.

WSTRAWINPDAY - READ IN 1 DAYS WORTH OF DATA FROM ASCII FILE

[Previous Routine] [Next Routine] [List of Routines]
NAME: 
wstrawinpday - read in 1 days worth of data from ascii file

SYNTAX: n=wstrawinpday(yymmdd,bar,inpdir=inpdir)
ARGS:
  yymmdd: int   yymmdd of date for file (ast)
 inpdir : string input dir to read file. def: '/share/orion/'
RETURNS:
      n:  int   number records input
 bar[n]: struct input data
               
DESCRIPTION:
   Input a days worth of wst data from the daily raw:
wst_yymmdd.txt. 
	The data is loaded into the {wststr) array bar. 
The file can have 1 or more minutes from the next ast day
Since the file rename occurs 1 minute after midnite

(See /pkg/rsi/local/libao/phil/wst/wstrawinpday.pro)


WSTRAWINPRECS - READ IN RECORDS FROM ASCII FILE

[Previous Routine] [List of Routines]
NAME: 
wstrawinprecs - read in records  from ascii file

SYNTAX: n=wstrawinprecs(lun,nrecs,bar)
ARGS:
  lun : int     from file open
  nrecs: long   number of entries to read
                use this to skip recs with bad dates
RETURNS:
      n:  int   number records input
 bar[n]: struct input data
               
DESCRIPTION:
   Routine reads nrecs worth of data from the file pointed to by lun.
Lun should be assigned to the oriondata.txt ascii file 
(written by the orion weather station). The routine does no positioning
before starting to read (so you should do a rewind if you don't know
where you are positioned in the file.
	The data is    loaded into the {wststr) array bar.
