That is the mapping between the space wavelength, spectral order and the space sample x , line y in the raw image. ... Sections and describe the solution of this mapping. The second step in the reduction, described in Section , is to estimate the image background. ... In the rest of this Section the algorithms used in each step of the reduction are described. ...

It is a matter of common knowledge that in processes of genesis and evolution of many solar phenomena participate magnetic fields of sunspots. ... As a basis for formation of the database we take data on magnetic fields, collected by set of observatories during many years of observations. ... Section "Magnetic field data" contains data of magnetic field observation for separate sunspots, presented in standard text format (ASCII). ... Description of structure of these files is presented here . ...

... The analysis and reduction of the STIS flanking fields proceeded in similar fashion as for the imaging of the Main STIS Field. ... The DARK calibration reference file used in the CALSTIS data reduction steps was constructed using a 'delta-dark' image appropriate for the epoch of the flanking field observations. ... DRIZZLE drop-size used for the flanking fields was a "pixfrac" of 0.8. ... For information on the data reduction, please read first the technical information for the Main WFPC2 Field . ...
