i). study 29-32 are designed specially for all of compression schemes test, however, only study 29, 30 have generated useful fits files. Also the selection of compression scheme was done in eis_mk_study tool, rather than eis_mk_raster, thus there was no scheme inofrmation in these fits header. In this case one needs to manually find out the scheme for every fits files by study 29, 30.

The following links show DC factor variation in different scenarioes (eg. AR, QS for SCI_OBJ, 1", 2", 40", and 266" for SLA). A conservative estimation of avgerage factor is indicated by orange dash-line on the plot, which could be used to improve EIS planning tools when the number will be approved/corss-checked.
