 A. PHOTMETRIC DATA ACQUISITION TO FIND PLANETS
 B. OUR METHOD
    1. Observing the shaddow of a planet passing in fron tof the
       planet it is orbiting.

       a) Equipment
       b) Computer Programs
          1) FIT
             a> (LAB BOOK 6/26)  Takes archived data (*.ARC) and does most
                of the data reduction.  Produces two diles: DATA.SUM &
                DAT.DAT.  DAT.SUM provides information on the nightly
                obsevations.  It givers the error, air mass, and a
                calculation of the extinction coefficient function.  DAT.DAT
                is used by TAB to generate the final output.  FIT requires
                two files.  (*.TBL)  They are some sort of star charts.
                These two programs were written by BOB HOGAN in Fortran

                                         REDUCING PHOTOMETRIC DATA
                                         From Fairborn Observatory
                                         in  the ATIS file  format

                                    After the data has been downloaded from the Fairborn 
Observatory computer, the data is run through two programs that process it and place it 
in a usable form.  The first program is FIT.  FIT accounts for the sky and dark values.   It 
also calculates an extinction coefficient.  It does NOT use the extinction coefficient.  Bill 
requested this so he could put in his own extinction coefficients.  The data is intially 
stored in archived files (Example: A0448002).  The output is in two files: SUM.DAT and 
DAT.DAT.  SUM.DAT is an ASCII file that is to be viewed with an editor.  It contains a 
summery of the individual nights.  It can be used to figure out what was happening at the 
telescope. The file contains the following information:

                                             SUM.DAT

                         star      --  star observed, HD number
                         time      --  average time that a set of stars were looked at
                         exti      --  the calculated extinction coeffecient
                         rel error --  relative error
                         airmin    --  airmass minimum value
                         airmax    --  airmass maximum value
                         #         --  number of times the star was looked at
                         plus information of the extinction function found

                The second file, DAT.DAT, contains the information to continue the data 
processing.  It is used by TAB to correct the data using the extinction information.  The 
current version of FIT is FIT2.  This will probably change soon.  FIT takes a large 
amount of time to run.

                     There are two files required by FIT: REFSTAR.TBL and CATALOG.TBL.  
FIT will not work without these files.  They are star catalogues for the program.

                                            REFSTAR.TBL

                          Group     --  The group of stars that this is a reference for
                          Star      --  HD # of the star
                          Magnitude --  !@#??  Accepted value?
                          Color     --  !@#??  ??

                                            CATALOG.TBL

                          HD #      --  Catalogue number
                          RA        --  Right Assension
                          DEC       --  Declination
                          M         --  Magnitude
                          CI        --  Color Index ??
                          E         --  ??

          2) TAB
             a> Command List and Description
                1> Days - List days that will processed.  Days are in the last three places of the 
Julian date.  EX:
                   a: DAYS 1 500    -   days 1 through 500
                   b: DAYS 3        -   only day 3
                2> Color [Star #]   - generates a color table for all selected days.  Table 
contains all the data points for the particular night.  # is the HD catalogue number.
                3> Print - send the buffer to the printer
                4> Night [Star #]   - generates table of data at one averaged point per night.
