Pre-Processing for Image Synthesis -- Transfer of Raw Data

You have to transfer the raw-data and 'SZ' files (Appendix A.3 and A.4) from NSRO archive (Appendix C) to your computer through the network before synthesis of the NoRH images.


Note ! The size of one raw-data file is about 16 Mbytes (that includes 10 minutes of data, i.e. 600 image frames ). We strongly recommend the users who are far away ( in the sence of the network) to request us to send the data to you by ordinary mail as a form of CD-ROM (Appendix C).


(1) Basics

For example, to transfer the raw data that is necessary to synthesize one frame (image) every 600 seconds between 1997-4-20 1:30 UT and 3:30 UT,
IDL> st_time='1997-04-20 1:30:00' $<$CR$>$
IDL> ed_time='1997-04-20 3:30:00' $<$CR$>$
IDL> interval=600 $<$CR$>$
IDL> norh_trans,st_time,ed_time,interval $<$CR$>$


(2) Images at specific times

To transfer the raw data that is necessary for synthesis of images at specific times,
IDL> time=['1997-04-20 1:30:00','1997-04-20 1:40:00' ,' 1997-4-21 2:00:00'] $<$CR$>$
IDL> norh_trans,time $<$CR$>$


(3) 34GHz

To transfer 34GHz data,
IDL> norh_trans,time,freq=34 $<$CR$>$


(4) Event-mode

To transfer event-mode data,
IDL> norh_trans,time,/event $<$CR$>$
