A11.2.3 Common Blocks (continued)
Blocks for PLOT RATES
The common blocks in this section are mainly used by PLOT_RATES, although many are also used by other programs.
AXIS_LIMITS
common axis_limits, rlow, rhigh, tlow, thigh, llow, lhigh, dlow, dhigh
| rlow | float | scalar | Minimum rate or flux |
| rhigh | float | scalar | Maximum rate or flux |
| tlow | float | scalar | Start time |
| thigh | float | scalar | End time |
| llow | float | scalar | Minimum latitude |
| lhigh | float | scalar | Maximum latitude |
| dlow | float | scalar | Minimum distance |
| dhigh | float | scalar | Maximum distance |
The values in this block are used only when manual scaling has been selected by SCALING. The times are hours after the start of the first day present in the data to be plotted.
CHLIST
common chlist, channels, old__chans
| channels | string | array(variable) | List of the channel names to be plotted. |
| old__chans | string | array(variable) | Save the original channel names when a ratio plot is made. |
DATA_ARRAYS
common data_arrays, rates, times, accum,
flux_fact, ndata, spin_one, $
raw_rates, scdist, sclat
| rates | float | array(variable) | The rates (or fluxes to be plotted). |
| times | float | array(2,?) | The start and end times for each of the rates. |
| accum | float | array(variable) | The accumulation times for each datum. |
| flux_factor | float | array | Flux conversion factors used for each channel. |
| ndata | integer | scalar | The number of valid rates in the arrays. |
| spin_one | integer | scalar | The spin number of the first time. |
| raw_rates | float | array | The rates array without background subtraction. |
| scdist | float | array(2,?) | The spacecraft heliocentric distances in au. |
| sclat | float | array(2,?) | The spacecraft heliographic latitude. |
This block contains the actual data to be plotted. The accum field is only used for data for which error bars are available. Its use is abused by track data!
DUTY_CYCLES
common Duty_cycles, chduty
| chduty | float | array | The duty cycles for each selected channel. |
Used to hold the list of channel names so that they can be added as a key at the bottom of a multiple channel plot and remembered for interactive channel selection.
FILTERING
common filtering, fmode, dwid, thresh, drop
| fmode | integer | scalar | Type of filtering to be used. |
| dwid | integer | scalar | The width of the filtering window. |
| thresh | float | scalar | Threshold for spike removal filtering. |
| drop | integer | scalar | Remove dropouts or not. |
This block contains the filtering options for PLOT_RATES.
FLAGS
common flags, filter_flag, average_flag, fmerge,
replot_ok, ratio_flag, $
user_ratio, movie_flag, sector_flag, m_wid_flag,
bg_flag, $
pos_ok, index_formed
| filter_flag | integer | scalar | Have the current data been filtered? |
| average_flag | integer | scalar | Have the current data been averaged? |
| fmerge | integer | scalar | Set if forced sector averaging is in use. |
| replot_ok | integer | scalar | Can PLOT_RATES replot without re-reading? |
| ratio_flag | integer | scalar | Has a composition ratio been computed? |
| user_ratio | integer | scalar | Has a user ratio been computed? |
| movie_flag | integer | scalar | Were the last data read into data_arrays for PLOT_RATES or MOVIE? |
| sector_flag | integer | scalar | Has the sector count been messed about |
| m_wid_flag | integer | scalar | Is a movie displayed in a draw widget or a normal window? |
| bg_flag | integer | scalar | Have backgrounds been subtracted? |
| pos_ok | integer | scalar | Are the settings suitable to plot against position |
| index_formed | integer | scalar | Have spectral indices been computed? |
An assortment of binary flags needed to prevent meaningless plots being produced.
