+# Run Group K, Spring 2024, Pass 1
+
+We will use SIDIS skims from two datasets: one for a 6.4 GeV beam, and another for a 8.5 GeV beam; we will keep them separate, to be consistent with what we did for Fall 2018 RG-K data:
+- `rgk_sp24_6.4GeV`: from `/cache/clas12/rg-k/production/recon/spring2024/pass1/6395MeV/dst/train/skim1`
+- `rgk_sp24_8.5GeV`: from `/cache/clas12/rg-k/production/recon/spring2024/pass1/8477MeV/dst/train/skim1`
+
+Before anything, cross check the train and DST run lists:
+```bash
+bin/qtl xtrain /mss/clas12/rg-k/production/recon/spring2024/pass1/6395MeV/dst/train/skim1 /mss/clas12/rg-k/production/recon/spring2024/pass1/6395MeV/dst/recon
+bin/qtl xtrain /mss/clas12/rg-k/production/recon/spring2024/pass1/8477MeV/dst/train/skim1 /mss/clas12/rg-k/production/recon/spring2024/pass1/8477MeV/dst/recon
+```
+
+## Reheat
+
+**TODO**:
+- [ ] check if needed; see Fall 2018 RG-K notes
+- [ ] if reheating is needed, fix `qtl histogram` paths below
+
+## Run monitoring
+
+> [!IMPORTANT]
+> Check any run-dependent settings in `qa-physics/monitorRead.groovy`, such as beam energy.
+
+```bash
+qtl histogram -d rgk_sp24_6.4GeV --flatdir --focus-physics /cache/clas12/rg-k/production/recon/spring2024/pass1/6395MeV/dst/train/skim1
+qtl histogram -d rgk_sp24_8.5GeV --flatdir --focus-physics /cache/clas12/rg-k/production/recon/spring2024/pass1/8477MeV/dst/train/skim1
+```
+
+## Double check that we have all the runs
+
+> [!IMPORTANT]
+> In case any runs disappeared from `/cache` while running monitoring or reheating, be sure to cross check the output runs with those from `/mss`
+
+## Make timelines
+
+Make the timelines, separately for each of the 2 datasets:
+```bash
+bin/qtl physics -d rgk_sp24_6.4GeV -p rgk/pass2/qa/sp24_6.4GeV
+bin/qtl physics -d rgk_sp24_8.5GeV -p rgk/pass2/qa/sp24_8.5GeV
+```
