8. Level-0 Data of Hinode The Level-0 data are not calibrated. The fits files are in Level-0 data. Level -1, 2 obtained after calibrating the data with SSW software, which includes dark subtraction and flat fielding etc. SOT FITS Data Format http://solar-b.nao.ac.jp/hrc_e/lv0_desc.shtml

9. Filenames of SOT Level-0 fits files 1. FGyyyymodd_hhmmss.s.fits FG Filtergram. Ex: G-Band, Ca II K, Blue continuum, Na D1 etc. 2. FGIVyyyymodd_hhmmss.s.fits FGIV Shuttered Stokes I and V images. 3. FGSIVyyyymodd_hhmmss.s.fits FGSIV shutterless Stokes-I and V images. 4. FGSIQUVyyyymodd_hhmmss.s.fits FGSIQUV shutter less Stokes I, Q, U & V images. 5. SP4Dyyyymodd_hhmmss.s.fits The Stokes spectrum data (SOT-SP), 4D Stokes I, Q, U & V. The unit of the file is one slit position, not one raster. yyyy:Year, mo:Month, dd:Day, hh:Hour, mm:Minutes ss/ss.s:Second

10. Examples of SOT/FG filenames Each data sets are arranged under the subdirectory /hinode/sot/level0/year/month/date/FG/hour/filenames Ex: /disk/jf1/HINODE/sot/level0/2006/12/28/FG/H0000 /disk/jf1/HINODE/sot/level0/2006/12/28/FGIQUV/H1700 /disk/jf1/HINODE/sot/level0/2006/12/28/SP4D/H0000 Filenames of Level-0 data. Ex: 1. FG20061228_00253332.2.fits 2. FGIQUV20061228_170032.1.fits 3. FGIV20061228_103518.2.fits 4. FGSIQUV20061228_170212.5.fits 5. SP4D20061228_00645.4.fits

11. Routines to calibrate the FG/SOT data To check the SOT data catalog. idl> sot_cat,'2006-10-28','2006-10-29',sotcat To check the available data between 2006-10-28 to 2006-10-29, the structure sotcat contains the information. Then one can use the following routine to see the files. idl> files = sot_cat2files(sotcat) All the names of the files and their paths are stored in files. Idl> read_sot,files,index,data To read those files use the routine read_sot and the calling sequence is as above. Idl> sot_cat,'28-Dec-06 15:00','28-Dec-06 18:00',index,files,/level0 One can use the above arguments to check the data between 15:00 – 18:00 UT of 28 th December 2006. The file names and their paths are stored in files. To read and calibrate the broad-band image data. idl> file = findfile(‘*.fits’) idl> mreadfits, file,index idl> ss = where(index.WAVE eq ‘Ca II H line’) Or Index.Wave eq ‘G band 4305’ or ‘CN bandhead 3883’ or ‘blue cont 4504’ or ‘red cont 6684’ or ‘green cont 5550’ Idl>fg_prep,file(ss),index_out,image_out,/despike,/display,/float,/verbose,/tf_deripp le,/outflatfits,outdir=‘/disk/data/ravindra/hinode/’ Process an SOT BFI or NFI filtergram, magnetogram, dopplergram, or Stokes set despike - cosmic ray removal, /no_flat - skip flat fielding (This option is necessary for NFI.), /float - return images with floating (default: integer), /quiet - set for fewer messgaes, /verb - set for lots of messages Idl> write_sot,index_out,data_out

12. Rigid Alignment of the FG images idl> fileb = findfile('reg20070406_*.fits') idl> mreadfits,fileb,indexb,datab Idl> fg_rigidalign, indexb, datab, index_outb, data_outb, dx = 512, dy =512, x0 = 10, y0 = 10, nt = 40 dx=the x-dimension of the box in which image-to-image correlations are calculated. Default = 256. dy=the y-dimension of the box in which image-to-image correlations are calculated. ; Default = 256. X0: the x-coordinate of the lower-left corner of the correlation box. ; Default = image center. ; Y0: the y-coordinate of the lower-left corner of the correlation box. ; Default = image center. ; Nt: the number of images correlated at one time, i.e. the number of images ; assembled into a subgroup and aligned with respect to the first image in the group. ; Default = 4. Set this parameter to be less than the number of images over which the ; correlated structures in the images change significantly.
