EIS_XSTUDY#

The eis_xstudy routine is actually a component of the EIS Planning tool, and is used in both the construction of a timeline (eis_mk_plan) — to load something from the OSDB (official studies database) — and in eis_mk_study, used to select a study for modification in your own personal database before submission to the OSDB.

Walk-through#

The eis_xstudy interface.#

Below is an example of the widget that appears in SolarSoft when you type eis_xstudy:

Study list#

The top panel contains a list of all the studies in the database. I've cheated a little bit, in the sense that I've already scrolled down the list in the upper panel and chosen Study ID #267, the catchily-named JS_CH_140x256p

(There's a button at the top of this interface marked View/Edit Study Description. I'll come back to that in a while.)

Information bar#

In the status bar immediately beneath the study list is a sort of information bar: here you can see important information such as the amount of data that the study is expected to generate in kbits (this is approximate, since compression factors vary a little from dataset to dataset), the duration in hours minutes and seconds (fixed, but with a little margin added), and the consequent rate of telemetry from EIS to the Hinode Data Recorder (DR).

The volume here is probably one of the most important factors, since it determines how many times (if any!) a study can be run during an OP Period — see SbandObservingInfo for what this means in practice.
