file: jsoc-manual.txt = RR manual for JSOC im_patch cutout service init: Dec 8 2013 Rob Rutten Sac Peak last: Jun 17 2021 Rob Rutten Deil note: sometime 2016 this manual became obsolete, see my sdo manual NB: this manual is no longer used or needed --------------------------------------------------- This manual describes how to get SDO data for "cutouts" (= small fields of view matching other telescopes, e.g. the SST) using the im_patch service on the JSOC exportdata website. Since spring 2016 this isn't needed by me anymore since my sdo_orderjsoc.pro does the ordering from an IDL session, and my sdo_getjsoc.pro does the dowloading from IDL too. I therefore cut the below parts out of my sdo-manual.txt in case I still need these notes in future. Step 1: define your desired SDO cutout sequences ------------------------------------------------ find area of interest: from GBO data or daily movies or JHelioviewer define (X,Y) of cutout center precisely for the start time of the desired SDO data set (solar rotation moves your target up to 10 arcsec/hr) sdo_featurelocator,datetime,wav,imagedir=imagedir # find feature (X,Y) e.g.: sdo_featurelocator,'2014-01-01 00:00','1600' zoom in precisely to the recognized feature and click for coordinates define JSOC series identifiers by copy-paste + editing of: aia.lev1_uv_24s[2013.07.29_14:00/120m][1600,1700] # start, length, wavs aia.lev1_euv_12s[2013.07.29_14:00/120m][304,171,193] # or more AIA hmi.M_45s[2013.07.29_14:00_TAI/120m] # magnetograms hmi.Ic_45s[2013.07.29_14:00_TAI/120m] # continuum hmi.V_45s[2013.07.29_14:00_TAI/120m] # Dopplergrams [NB -in case of problems defining the desired sequence specifier: <> click on RecordSetSelect paste/build series identifier into window, NO return click check count click tab on top "Export Data" click export button yes, leave this page click export redo the exportdata page] Step 2: get "im_patch" cutout sequences from JSOC (both AIA and HMI, fast) -------------------------------------------------------------------------- request the first series: <> paste first series identifier into upper RecordSet window hit return or click Check count Method > url-tar click Enable Processing active click im_patch active keep Tracking enabled, Register and Crop not enabled maintain the default reference time = start time of requested series (NB: setting a different reference time ??may?? spoil HMI coutouts) set LocUnits for (X,Y) = arcsec from center (not px, 0.5/0.6) specify X and Y of patch center set box size scale: arcsec (not px) set box width (for xga movies: minimum 55 or 110 or 220 or 440) set box height (for xga movies: minimum 43 or 85 or 170 or 340) Check params in im-patch box: must have "OK to submit" behind it ?? Compression > Rice Protocol: FITS notify: email address click Check Params for Export click Submit Export Request when green ignore size estimate # still is way too large wait for grey Request Export Status (or wait for email) note Record Set string + JSOC request number (raise page) in emdatasdojot request the other series (repeat for each): paste next series identifier into upper RecordSet window in im_patch box click Update Reference Times click again on "Check Params for Export" # even when green wait until Submit Export Request is green click green Submit Export Request wait until this goes grey after red again note request identifier wait for the processing to be done or the confirmation email Step 3: download requested data sets when ready, untar, check field of view ------------------------------------------------------------------------------ click Request Export Status when data complete: right-mouse download link or in "export complete" email: right-click > open link right-click > "Save as" post-download shell command startup: mkdir datadir cd ~/Downloads tar xf *tar rm -f *tar cd datadir mkdir level1 cd level1 mvfromdownloads *.fits cd ..
